I felt like I was watching Forrest Gump without the humor. Remember how the odd guy was content with himself because he didn't know any different and he just fell into unusual situations? It was the same in Button. The people around him acted oddly, either treating him too much like an insider or too much like an outsider.
The relationships didn't have much depth because he kept traveling and there were too many of them. It felt choppy. It tugs at your heartstrings at the end by using a time-tested formula of the parent/child relationship.
