Well, gotta go with the classic of them all here : Catwoman.
Of the ones I've seen: Steel.
I want to say Catwoman, but I'm not sure it's actually a comicbook adaption. There are no comicbook characters in it, for starters.
Howard The Duck
Red Sonja was very, very bad... Did have an awesome score by Ennio Morricone though.
ETA: and oh gods yes, Lucifer.
And Inhumans, if we're adding tv series now.
If TV shows are eligible, I'm going with Birds of Prey.
Defending Time
Howard the Duck is Awesome.
Iron Man 3 is also Awesome people need to get over the Mandarin twist the real tragedy of that film was Perlmutter's interference and forcing them to change the villain from Maya who Cleary was given the set up with a real connection to Tony to Aldrich.
Batman and Robin and Catwoman are so bad they become good.
Now the Bad
Steel (Just bad on every level acting, story, design, and as a adaptation of the Character).
Now for the it's a good film but bad adaptation Dark Knight Rises also while fun to watch for it's Schlock factor Judge Dredd with Stallone.
I hate Batman and Robin as much as the next guy, but I kinda feel like it's disqualified. It was clearly trying to send up the Adam West, Superfriends campy era of Batman without even trying to seriously adapt the character as it currently was. I personally think Dark Knight Rises is much more egregious in terms of adaptation.
Genuinely shocked to discover I'm not the only one who didn't like Thor Ragnarok
Catwoman is not a comic book movie, it's a terrible movie riding on the coattails of the character with the same name from Batman lore, so I will never include it in these discussions.
We want to talk Norse mythology? Thor: The Dark World and Son of Mask are unwatchable to me, with the latter being truly terrible.
Batman Returns is the worst of the first series, it's not good or even decent like its predecessor, and it's not pleasantly bad like its two immediate follow ups, it's a mediocre movie that receives way too much praise it is unworthy of. It is neither a good Batman movie nor is it a good fairytale kind of story.
Batman V Superman, both cuts.
I'll bring back Howard the Duck and Man-Thing.
TRUTH, JUSTICE, HOPE
That is, the heritage of the Kryptonian Warrior: Kal-El, son of Jor-El
