It's probably the worst movie I've ever seen. But then I worked at an IMAX/museum during last summer when they were showing it, so I've seen it more times than is rational.

Interesting tidbit: I worked at the Smithsonian museum in the movie (where the big blackbird transformer is) as a summer job. Everyone kept asking if we got to meet the cast. I told one guy that we all had lunch with Megan Fox and Shia LaBeouf when they were filming. I didn't but he believed me. Or pretended to believe me.

Anyway the movie sucks.
