Number 2.

Night at the museum 2:Battle for the Smithsonian

More characters added,bigger museum aka world's biggest museum,movie was filled with excitement.However,I felt that 1 was better.
2 was just some battle,and most of the time spending on figuring out the "code" for the tablet and hilarious parts.
And the code was lame,Pi or π 3.14159265
-.- ...
One of the part where dark raider do some force on the Egyptian man was "CUT" off,
and this was shown on the trailer!!!

Next movie:

Transformers 2: Revenge of the Fallen (:

Yesterday night's,I dreamt of wild animals associated with a temple just opposite my house. -.-
