How much does comic accuracy mean to you in movies?

When stories are adapted into live action movies, how faithful do you want the writers/directors to be to the source material? Do character details need to be completely accurate or should there be some wiggle room for interpretation? Should villains be nerfed so that they're beatable in a single movie (looking at you, Doctor Doom)?

If you had it your way, what would this dynamic look like? Any different than what we currently have?
