I watched the first 11 min of Night At The Museum Secret Of The Tomb.

I got to the part when they were giving the presentation at the dinner banquet and then the ancient Egyptian tablet started affecting Roosevelt and all the museum characters and everyone went berserk and panic ensued, etc etc

Just more of the same boring mayhem and recycled visual gags that were in the first 2 movies.

Not going to finish watching the rest.

Looking back at my IMDB rating for the first 2 films, I gave each one a 1 out of 10 so I doubt this one would be better if even that than the previous 2 films.
