Gwenda Bond calls Brothers Grimm a "terror of mediocrity." That's too bad, I disagree. I thought it was fun and exciting and filled with interesting turns on Grimm fairy tales. It also had the single creepiest scene having to do with the gingerbread man I've ever seen.
In her defense, the movie did have a near-Hollywood ending and was nowhere near the brilliance of Terry Gilliam's best films (Brazil, Twelve Monkeys), but that in no way means this was a bad film. I had a great time.
The movie gets a rotten rating of 38 percent at Rotten Tomatoes. So more than a few people agree with Ms. Bond. Although, I might note that most of the bad reviews still say nice things about the movie. For instance, here's Roger Ebert:
Terry Gilliam's "The Brothers Grimm" is a work of limitless invention, but it is invention without pattern, chasing itself around the screen without finding a plot. Watching it is a little exhausting. If the images in the movie had been put to the service of a story we could care about, he might have had something. But the movie seems like a style in search of a purpose.
My recommendation is go see it for yourself. But maybe read a few reviews first to decide if it's your type of film.
