You must have a different definition of 'adventure game' to me.
At least with Season 2, Telltale already knows of the flaws that Season 1 had and what didn't go down well with people, and the team does listen to feedback. They can design with that in mind, instead of having to try and address failings midway through a season. (The first three games in the series were nailed down before the first feedback from episode 1 was available, so not much could be done to address the issues). I thought that the latter half of the season was much better than the start of it.
