While this is a Zach Braff movie, it's Josh Gad who has a lot of scene-stealer scenes. Not sure if you could (or should) compare him to early Jack Black, but if you do that analogy/comparison on the degree of how funny they are, I guess you can. Although Gad seems a bit more low key of course (and not only in this, but other movies he did).

Zach is doing his usual thing, which isn't bad, but might feel a bit like the same to viewers. And still the movie is able to get you towards the end, if you have a soft spot for drama. Like I said, I credit Gad mostly for that, but the kid actors are not bad either. This drama is not as good as some others I watched in 2014, but it's more than decent enough
