I thought listening to Kevin Costner drone on for a couple hours as a dog's inner monologue would be tedious, but the nuggets of wisdom peppered with the occasional witticism provided ample entertainment. I often felt like I was watching the "Thoughts of Dog" Twitter account played out in cinematic form. I absolutely loved both Milo Ventimiglia and Amanda Seyfried in this. The daughter was also played especially well by Ryan Kiera Armstrong. The relationships between themselves and also with Eve's (Seyfried) parents was perhaps a bit banal at times, but overall was still believable and endearing - although I felt like hitting the dad with my car at several points.
Afterwards, I overheard several people tell the studio rep that they hadn't expected the movie to be a "tear-jerker", and the sobs coming from the gentleman seated next to me seemed to confirm that. However, I found the story to not be overly sorrowful or sad, but inspirational. A guide, if you will, for how to become an exemplary person shown through the filter of a dog's belief that by gaining this knowledge he'll be reincarnated as a human in his next life. (I know it sounds silly, but it was actually quite poignant.)
