I saw The Adventures of Rocky and Bullwinkle movie (came out in 2000) on T.V. about 4 or 5 months ago. I was surprised that it was actually a good adaptation -- watching the movie seemed very much like watching the cartoon.
Seeing as most movie adaptations of classic T.V. series aren't very good {IE Dragnet, Beverly Hillbillies, The Flintstones, etc. -- even the 2 movies for the Addams Family are merely so-so} it's dissappointing that Rocky and Bullwinkly movie didn't do better. Although that could be due in part to a poor ad campaign, I don't recall seeing trailers or tv spots (though I could have forgotten about them).
