For me, someone saying "I'm tired of superhero movies" makes as much sense as saying "I'm tired of sci-fi movies." Maybe you just don't like the genre. I don't like westerns in general, but I recognize some of them are great despite the genre they occupy.
In this upcoming Superman movie I'm hoping that the concepts of Superman being a god that wants to be a man around men that want to be gods is central.
I don't think you're gonna get the later half of that. I'm very excited for Man of Steel. They're almost positioning it as an alien invasion film rather than a superhero film, which I like.
I like superhero films which blend with another genre. Nolan's Batman films are superhero/mob films. (The Dark Knight is almost a pure mob film which accidentally contains Batman.) The next round of Batman films should be superhero/detective blends, since we just aren't getting enough "World's Greatest Detective." And enough with the "fighting terrorists" angle, focus on fighting criminals. Thor is a fantasy blend, Captain America is a war film blend, and The Matrix (which is most definitely a superhero film) is a superhero/kung-fu/cyberpunk blend. Superman is the closest to a pure superhero flick, which is why Superman is often derived as "boring," which is why the alien invasion angle is exactly what is needed. Like it or not, the Spiderman films are rom-com blends, which I think they need to move away from to infuse some freshness into the franchise. They hinted at a murder-mystery blend for the re-boot but didn't deliver, which is too bad. The comics had the longest-running mystery ever (Hobgoblin), and I'd love to see that sort of story adapted to the screen.
I also love the meta-commentary superhero films, like Defendor and Watchmen and Super and Kick-Ass. The inherent absurdity of costumed vigilantes just invites intelligent deconstruction. I just showed Watchmen to someone two days ago, and I still love it. I'd welcome a re-make in a few years which focuses on the mindsets of the characters and just tones down the blood, swearing, and sex somewhat. It also needs a faster pace, which was also a problem in Ang Lee's Hulk, which was otherwise a solid superhero/psychological-mystery flick.
The only pure superhero films that work were the X-Men films, but that's because they're really a meta-commentary on tolerance and intolerance.
Otherwise, there haven't been many superhero movies lately that have really done much for me.
I feel the opposite. They're getting better, not getting worse. The Amazing Spiderman was better than Spiderman 3, X-Men First Class was better than X-Men 3 and Wolverine Origins. And The Avengers just amazed me: perfect character interaction.
Stuff I'm excited for:
Man of Steel
X-Men: Days of Future Past
Iron Man 3
Kiss Ass 2
Coming stuff I'm indifferent to:
Guardians of the Galaxy
S.H.I.E.L.D. tv show
Sh!t I'm not getting and am quite pissed about
A Hulk sequel
Stuff they screwed up but should take another crack at anyway:
Green Lantern sequel
Stuff that's too awesome for mere Hollywood to ever get right:
Alpha Flight. Hell, Marvel Comics itself couldn't get it right despite several promising re-boots and J. Michael Straczynski.
Stuff that still astounds me:
The character and performance that ruined Daredevil got her own film.
Someone could fnck up a film about Halle Berry in a skin tight suit.
