Trailer: World's Greatest Dad trailer
This for me is Robin William's comeback. He is funny here without trying to be funny which is the main point. It starts out with a look at Robin's dysfunctional relationship with his son. He is your typical loser late middle age dad trying to relate to his son which of course tries at every chance to resist or turn down his dad's attempt at being close.
All seems lost when an "accident" occurs in which Kyle (played by Daryl Sabara) which is this shallow teenager which is only interested in sex and getting laid dies. Lance (Robin Williams) is heart broken until an unlikely turn of events causes him to benefit from his son loosing his life. The not-so-hot father son relationship is examined here, Lance trying to decide whether it would be right to benefit from the perception his son's death. I will not reveal here what the turn of events are as I think it would be better for you to watch it yourself. Lance is less than conflicted here as the relationship with his son was not strong to start with and justifies to himself that his son's is better off dead.
To me Robin William's performance here is touching and low key, which is what I like about it. You don't sense his trying too hard and what comes through is truly one of his strongest performance till date. Alexie Gilmore, too as the unfaithful source of his attention turns in a passable performance but the thing that sealed this movie for me was Robin's performance. I heard that Robin took a 2 months hiatus after the movie August Rush, if that be the case welcome back Robin!
