Batman v Superman: Dawn of Meh
Spoilers incoming
This didn't have to be a bad movie. There are kernels of good things in here. At its core, this could have been a really good superman movie, with Batman as a supporting character and antagonist. Everything wrong with this movie comes down to time, and having to shoehorn in the beginnings of a justice league movie.
As much as I loved finally seeing wonder woman on the big screen, she was pointless in this movie. She's there for like a minute. She should have been cut and given her own movie, I really think Gal Gadot could kill it in her own Wonder Woman film.
Batman needed more development. Ben Afflec gives a wonderful performance for what there is, but I wonder how much of his performance got left on the cutting room floor. I could accept the new, murderous Batman had he been given more time. There are little glimpses. We see Wayne Manor in ruins, we see Robin's vandalized suit, we see tiny images to show how Batman got to where he is, but we needed more. We needed to see what broke the Bat, what lead to him being alone, everyone he cared about dead, and totally burnt out and no longer adhering to his code. You can go grim dark on Batman, he fits well there, and the image of this once hero fallen so far could have been the catalyst that the Superman introduced in Man of Steel needed to become the big blue boyscout. Batman could have succeeded in teaching supes what not to do, and would have fit Batman's paranoia, afraid of what superman could become because he knows what he became.
Doomsday? No, save that for a death of superman movie. That should have been your justice league movie.
