I just saw it. It was definitely not worse than the second one. Most definitely not. The length wasn't ridiculously bad for the actual amount of action therein either. Sure it could have been paced better, but there weren't any vast amounts of actionless snoozefests the likes of which regularly plagued RotF. My only major complaint is that the deaths were lame. All of them. Every last one. Terrible.
