As I've discussed before, the BttF license is bringing Telltale the attention of a whole horde of people unfamiliar with not just Telltale, but the adventure genre as a whole.
Now, I know YouTube commenters and the like aren't known for having good ideas, but it does give one an idea of what the masses in general think, and there's a whole bunch of whining about how point-and-clicks are stupid, it should be a GTA clone, yadda yadda yadda.
Now, with any game/movie/book/whatever, disappointing somebody is inevitable. You can't please everybody, and you definitely shouldn't try to. However, point-and-click adventure games are admittedly a niche market (that doesn't mean they're bad, mind you. If I hated point-and-click adventure games I wouldn't post on Telltale's forums ;)), and I think maybe something should be done to help newcomers get familiar with the genre and realize Back to the Future is in capable hands.
