My problems with Season 2 (And TWD Game in general)
First, let me say that TWD franchise itself is a great one, and so is Telltale. I think Telltale makes wonderful products in general and puts a lot of work into their releases.
(TLDR at bottom)
Now, I might be a tiny minority holding this view, I'm not sure. I personally find the 'choices you make affect the game' to be kind of misleading. Yeah, most of the choices you make will have some minor dialog change, but overall, the game is extremely structured and linear. No matter what you do, no matter what choices you make. Sam the dog dies, no matter what you do Sarah dies, or x person dies, or x person leaves or x happens. Structure is one thing, having objectives is one thing, leading the player by the hand completely and not allowing them to actually affect the game world in large part is another.
The vast majority of the choices that actually made a difference in Season 2 were at the very end of episode 5 where things branch out for the start of season 3. Yeah, from the way it looked like, we might actually have some kind of impact with our choices in season 3, 'might.'
It bothers me that Telltale promotes the game on the idea that 'you' control the way the story unfolds and that you have a lot of replay value, when there really isn't much. I mean really, replay the entire game without ability to skip dialog, to see what? A 2-5 minute or so segment of dialogue unseen because you didn't choose to kill someone else? Or do something else?
My bet is that they don't want player decisions to 'significantly' change the game's outcomes because of A) It would create a lot of overhead in the writing department. 
It makes it so that new players can easily get into a season without having to buy previous content.
Aside from the 'You don't control your character at all really' aspect. I feel the game is relatively short, too short. Me personally, I don't play each episode as it comes out, I play them all in one lump sum. I started playing Season 2 and I completed the whole season in what seemed about off and on playing for about 6 hours, maybe less. It had very few actual locations, it made me feel like the budget for season 2 had been cut back significantly, although the character graphics looked better. For me though, I couldn't careless if the graphics were 2d and the game ran on DOS. I waited a whole year to play Season 2 and there just isn't a whole lot of a 'meal' of it. It felt like a snack or a small appetizer and I kept hoping that it would be a full course meal like I was expecting, but it was't.
Maybe it's just the way that Telltale designed it and that seems to be more for the casual gamer. They probably also hope to keep making further seasons, maybe even beyond Season 3 and continue to develop the video game portion of the franchise. Perhaps at the end of Telltale's work we'll have this large saga story of TWD in an adventure game. I still feel there should have been more than what there is.
Overall I love the story of Season 1 and Season 2, but I'm disappointed by these two things and I feel like continuations are just going to be the same kind of problem.
TLDR: I don't think Telltale let's us make enough choices of our own and actual impact on the story, nearly all of it is set in stone. I don't think each individual season has enough content, Season 2 especially.

I love the game and I agree with your points. Our choices haven't made much of a difference now I'm not sure whether it's because of the writing overload that you've stated or that it would just be too difficult for them to program into. What I would like to see in the next season is choices from episode 1 playing a huge part in the finale of the season. I have a good feeling that they will end up doing this since it's a ground for them to explore and it would make it a true "choice based" game. S2 episodes have been fairly short. I noticed this more clearly during episode 5 how talking to some of the characters actually made the episode more enjoyable where as in 203 and 204 you don't really get much of an opportunity to know your characters, talking about the past during a ZA might be a bit cliche but I think it's necessary so I hope telltale includes this for all the episodes next season. If these two issues were to be fixed the game could be near perfect really.
We have 4 save slots.... 4 dialogue options.... multiple decisions.... I think it has replay value.
We INFLUENCE the character, not control, sure we may control them when they are walking around, but the decisions we are givin are from the character, they put out suggestions for us and we influence which choice they make.
Oh wow the game is short... that's where replay value comes into play, and also, in my opinion, a good story is better than a long game.
One of the biggest reasons that Season 1 was so long was because of the large numbers of hubs and mini-hubs, they didn't move around too quickly in Season 1, but in Season 2 they had to keep moving to reach their goal, just because it's a game you still can't expect realism to just drift away.
Season 1 and Season 2 have enough content in my opinion. What they should do is make more than one DLC per game
It's hard for TT to make another season without repeating scenarios from season 1. They are doing a good job keeping the surprises coming. As said in one of the playing dead episodes, they want to keep new content coming and try to keep things fresh.
I go into playing these games with the mindset that the story will be tailored based on my choices but the outcome will inevitably be the same. It's kind of like tailoring a shirt, it might look different but a shirt is still a shirt.
Also, software engines and programming just aren't at the state of intuitiveness which we all would like to see. I get where your coming from I think we just need to wait for technology to catch up.
But can you imagine when it does, I think this forum will crash with multiple posts depicting unlimited scenarios and opinions. Trolls and flammers will be holding hands dancing naked around a bonfire in celebration.
One hour to until home time, hell yeah!
