seriously, most of them are trash...too many concessions are made to 'realism' (only in a design sense, story logic, characterization and dialogue do not have to be realistic by any means) and so much of what makes these characters interesting is usually lost in translation.
for every 'dark knight' or 'iron man', there's a 'ghost rider', spider-man 3, fantastic 4, punisher war zone, wolverine origins, superman returns, or elektra that'll make you want to gouge your eyes out.
you end up with captain america being a 'uso performer' who's embarassed of his costume. wtf?
plus, as a comic fan, most of them make me cringe and i hate people asking me about them lol
if you're going to adapt a comic like spider-man or superman cinematically, why not do it in animation?
