The biggest drawback of this film is the unrealistic grooming of these stone age people. Nicely trimmed beards, no different from today! As about $51m was spent on making this movie, that is not so hot.

The story is okay, but drawn out, making it boring and then also having to read what is being said. As they were not speaking any known language, why wasn't simplified English used instead? That would have made it certainly more watchable. The developing relationship between wolf and man was the only savior, creating interest.
