I liked it

It is a sweet little movie and Channing Tatum's biceps are nice to look at, but it is entirely improbable and depicts dog behavior in an over-simplified, misunderstood and negative way. It is nice that it brings awareness to TBI and PTSD in a positive light and in a pop culture context, but again, extremely over-simplified.

I found it sad and frustrating. Channing Tatum was self centered and kind of abusive to the dog. I like animals and want to see them treated well.
