First Class was a fun, solid movie mainly boosted by its two leads. Avengers was the ultimate summer popcorn movie, but there wasn't a whole lot of substance to the plot. I love TDKR, but the film definitely has it's ups and downs throughout the 165 minute runtime. It starts off kind of rushing into things, almost. The middle section is pretty slow, and the last hour is phenomenal despite a minor plot hole or two.
DOFP had everything I hoped it would and more. It took the best of First Class, the best of X2, and morphed them together to make the perfect X-Men movie for the post- TDK comic book movie world.
