No characters like this should appear in animated form first and build an audience. Catman shouldn't have his own movie nor should Clayface or Sgt Rock as they aren't big enough characters to warrant it on their own.

I don't think it was a bad movie it was fun and watchable. I think the problem is like most of the movies in this saga there doesn't seem to be any overall story like infinity saga that is tying this all together. It's just random movies with nothing pushing a casual watcher to get invested. That's why DC movies also failed towards the end of the dceu

Sorry Channing but I don't think his Gambit should get a solo film. It's too late and time start the X-Men fresh after Doomsday. I would say that Doomsday and the avengers film after could display heroes of projects from the past that didn't make it and a perfect way to bring in new characters.
