I think a lot of the weakness fans like you and me feel is because the first Zombieland was just so unique and fun. That and we have had a decade to think and wonder and wish for a sequel that leaves the sequel never being able to live up to what we wanted.

It is sad. Had they done a sequel two or three years after the first and it was like this I would probably be screaming from the top of Babylon how awesome it is.

It is hard to pinpoint the problem but fans like you and me have that feeling there is just something missing here. Not the usual sequel missing stuff though, something else.

Still a fun romp and worth the price of admission, just doesn't warrant multiple viewings too close together.
