I found the action in the DC Snyder movies to be exhausting, particular MoS's drawn out final battle. It sucks to feel bored watching a comic book slugfest that won't end. On Whedon and Marvel in general, I don't think the DC flicks have come anywhere close to matching the battle royale type fights that Marvel has done. Those scenes (e.g., Avengers, Civil War) are just fun to watch over again, with an eye towards trying to spot what each hero in the pack of 10+ are doing.
Bay is just plain horrible, and this is coming from a guy who loves Transformers, the franchise.
