We were quite surprised (shocked) by the first 15 minutes of the movie and almost shut it off. There is a lot of disrespectful talk (words/phrases like: ass, moron, idiot, jerk, shut up) and behavior between Kevin and his siblings. The dialogue between Kevin and his mother is also pretty heavy. The Playboy magazine mentioned in another reviewer's post is something we just did not call attention to and it was fine. At the time of this writing, the Sandy Hook shootings are still fresh in our minds. After Kevin realizes he is alone, he begins eating junk food and watching TV. He picks an old black and white movie, Angels with Filthy Souls, to watch. Although heavily exaggerated, the scene in which the gangster shoots another gangster with a semi-automatic weapon while laughing maniacally is really disturbing. My kids have never seen this kind of gun violence on TV or in film. The gunmen then continues shooting at the fallen body (which is shown being shot) while laughing. Look, I get that this part if important for the plot of the movie, but it was gratuitous and unnecessary.
After the first 20 minutes, the movie continues to be somewhat rude. Yes the pranks Kevin plays on the burglars are terrible, but they are obviously exaggerated (and funny). Yes, Kevin is smart and resourceful, but we felt we needed to emphasize with our kids that the pranks, which led to no real harm in the movie, would have a very different outcome in the the real world.
In the end, the movie ended up being OK, but the first 15-20 minutes really left a bitter aftertaste. I could have skipped this movie...and kind of wished that I had.
