I started perusing reviews immediately after seeing the movie but quickly had to stop, fearing that all the good digs had already been taken and that if it were inevitable that some of my adjectives would match another's, it wasn't going to be because I read that person's critique first.

But man, are some of them funny. I finally went back to Rotten Tomatoes to read all of the vitriol — and 20 percent of the fresh ratings — and have listed the best below, in no particular order.

A horrible experience of unbearable length. – Roger Ebert

Like watching paint dry while getting hit over the head with a frying pan. – Peter Bradshaw, The Guardian

A giant, lumbering idiot of a movie. – David Edwards, Daily Mirror

A 150-minute simulation of life in a garbage disposal. – Matt Pais, Metromix

The male teenage cinematic equivalent of snorting cocaine off a hooker's ass. – Garth Franklin, Dark Horizons

If you ever wondered what a movie would look like geared toward the underdeveloped brain of a gestating zygote...then Transformers: Revenge of the Fallen is the insipid illustration you've been waiting for. – Bill Gibron, PopMatters

After 149 minutes, I felt like I had been sitting in an aluminum garbage can while someone drummed on the outside with a wrench.
– Laura Clifford, Reeling Reviews

#transformersfail – Nell Minow, Beliefnet

Putrid, offensive, and life-sucking. — Dustin Putman, The Movie Boy

And finally, a man after my own heart:

Only an asshole could have made this film. — Rob Humanick, House Next Door
