That first hour or so is pretty messy. Lots of jumping between scenes that are completely unrelated to each other, it felt like the film had no flow at all for the first hour. Once everything was "caught up" it got pretty damn good though. Great action, Batman was awesome, WW was good, Supes was good, music was great. It did have similar problems as Avengers 2 in that it clogged up with future film setups, but that's par for the course these days. I'm hoping that 3 hour long ultimate cut will help the pacing/editing a lot. We'll see.
