Sincere and unexpectedly good, the film happily reintroduces another element of classic kids' movies: a tidy 77-minute run time.

"Bears" could have used a lot more science; more substantive information in the place of wacky one-liners. Still, the images trump everything.

Bonus points for all but eliminating the easy scatological humor. Does a bear (poop) in the woods? You won't find out watching "Bears."

However well-intentioned and supportive of various wildlife preservation associations these productions may be, the G-Rated docs are more interested in producing awww responses from little kids than teaching them about nature.
