Mr. Peabody and Sherman is a CG animated movie in which a talking, super intelligent dog adopts a human child as its son.  It also invented a time machine, and used it to travel back in time to meet historic characters, with absolutely no worries of changing history.  It does, however, deal with time paradox.  Since I love time travel movies, I find this movie fairly interesting, although it has less jokes than it should.  While I believe that having some serious themes elevate animated movies, e.g. Pixar movies like Toy Story series, here the father-son relationship issue, and dealing with the parents of a girl bully, are somewhat annoying and hurt the enjoyment of the movie rather than helping it.
