Hey now... Telltale makes point-and-click adventure games, not action - so this will be in the vein of Monkey Island, Sam & Max, and the recent Back to the Future game. Yes, if you're looking for a gritty action-y game, this is not it. But a clever, funny, story driven game - looks like it will do the trick based on their previous work. They do good stuff.
I do agree that it's an odd choice as far as genre. Optimistic, though...
