I would definitely recommend this film.
Absolutely the CGI is cutting edge and spectacular in it's own right, but the plot is also at times extremely moving, especially for a CGI film, and there were even times when I found myself not even caring that the characters were CGI generated.
It was a most pleasant suprise to find what I thought was going to be simply an entertaining animated movie, to not only be that, but to also be a very good treatise on the depth and breadth of love, and a wonderful microscope into the dynamics of a long-term relationship.
Call me cheesy, call me overly-romantic...call me whatever you want...but this movie provided some "lump-in-your-throat" "tears-in-your-eyes" choke-up moments.
Great film to watch with your significant other! A+
