I didn't necessarily get the idea that was as good as mystery men, just seemed like they were going for that. Or Kick-Ass (sorry, called this superbad in the last post), or The Incredibles, or maybe even My Super Ex Girlfriend. In other words, a comedy set in a world with lots of heroes who have more flaws than positives and mostly deal with piddly shit. Unclear if any of them have any actual powers from the trailer (other than the villain). No one (other than the spleen) had actual powers in MM or KA either.
If there's even 1 gag in this movie as good as the invisible boy who is only invisible when no one is looking, it'll be a winner in my book.
