Simple Plan Fanfics

So, is it just me, or do all these newer Superhero movies have the same problem in their third acts? They spend all this time working over all the various sub-plots and side character arcs in the first two-thirds of the movie - noble hero learns their destiny, grows into their powers, discover that their strength makes them duty-bound to protect the innocent, and they learn to abandon their arrogance for the simplicity of love, etc. - while they waste time making supervillains that are supposed to be tragic, sympathetic figures, only to turn into incredibly unconvincing Supremely Evil Beings 15 minutes before the end? I'm watching Thor, and I'm thinking - okay, alright, they're trying to make Loki a legitimate trickster, with a Shakespearean tragedy for an upbringing. Yeah, I'm cool with this. And then! I'm supposed to buy at the last second that all of that doesn't really matter because he's evil and just wants to destroy everything for some reason. Some convoluted reason that doesn't work because character motives in big stupid comic book movies have to be filtered through no fewer than five or six different plot threads, instead of being clean and simple natch), but I'd hesitate to call either one of those shows "hits." Nonetheless, all it really takes is an intrepid publisher willing to take a risk.
