Loved the story and of course Buck. You forget that he is digital dog as his personality is engaging. A stand out performance by Omar Sy as the postal delivery on dog sled!!! Overall enjoyable for everyone and Harrison Ford as the lost and grisily frontier man was very good.

The CGI dogs act too human. Disney always does this, but it's usually with their cartoon dogs. It doesn't work with a CGI dog and it distracts from the movie. I was called to suspend my disbelief way too often.

Unrealistic.

An enjoyable Jack London classic brought to life. Everyone will fall in love with the dog, who shows great character. A lot of life lessons in this movie.
