Weird, I really don't have any complaints about this movie. It was incredibly funny, entertaining, and absolutely everything that this movie needed to be. It doesn't go overboard or under board, it's honestly as good of a Deadpool movie as we were going to get.
The humor, action, and drama are balanced at the right level (obviously with the meta-humor taking precedent), and there isn't a moment in the film where I became uninterested. It balances the flashbacks and forward moments perfectly, and every side character gets just enough time to shine but not enough to become annoying.
For some reason, despite not having a single grievance against the film, I can't get my grade up to an A+, I just didn't love it enough for that. But I still found the film great and would watch it again, it's everything a Deadpool movie should be.
