i dont think they should flat out stop, but i think they should slow down a lot.

the only real plus i've seen in the last couple years regarding these flims is the fact marvel has its own studio now. and those movies do have more respect for the source material itself.
if you keep letting douce bag, ari gold type studio execs run these films we'll see many more wolverines then iron mans.
i think the real problem is the mentality of the people they give these projects to. they think, "comic book = corny" and run with that thought process. punisher is a perfect example of this. 3 times they make films about the EASIEST comic character to make a bad ass movie about and EVERY fucking time they have to make it corny as fuck.
and yes, these characters are infused with some corniness, no doubt. but you can bypass that and just make a GOOD FILM with a GOOD STORY (nolan, im looking at you. lol).
they seem afraid to put mature themes in these movies, and the audience suffers for it (people who made wolverine, im looking at you). if they gave these properties to people who gave a shit, then we wouldnt see so many mediocre and bad adaptations.

and i agree. animation is the perfect format to make these characters come to life. cause even with all these flicks, you'll be hard pressed to find any of them as good as the justice league series. MORE ANIMATION!
