I'm a big believer in the idea that the stupidity of a basic concept is determined much more by actual execution than the concept itself. A movie based on people making a movie that depends entirely on faking the star's presence in it? That sounds pretty terrible, but the end result was
Bowfinger, which is somewhat genius (Steve Martin, for a large chunk of his career, excelled at taking terrible-sounding concepts and making brilliant movies out of them). A movie about a robot invasion of earth? Could be non-terrible, but then look what happens when
Michael Bay gets involved. Roberto Orci and Alex Kurtzman wrote both
Star Trek and
Transformers: Revenge of the Fallen. We all have days when we're hot and cold at the bat.
With that in mind, it's important to remember that while Disney's "
let's have the theme parks come alive at night" movie, much like the
Night At the Museum movies, is likely to be terrible. But that's because the concept is the point, rather than the jumping-off point. People who feel otherwise would be wise to remember and revisit
Don't Eat the Pictures, which proves definitively that you can make a funny, sweet, thoughtful movie for children based on the idea that there is more to a museum than you can see during business hours:
Bless Sesame Street.
