I couldn't stand all the re-editing that went into Young Adult to make it so bland. Reitman began to move toward "boring" when he saparated from his wife who helped write most of his films and said he wanted his kids to like them.

I would rank Reitman's movies like this
1.Up in the Air (2009) - 8-8.5/10 (my #2 movie of 2009)
2.Thank You For Smoking (2005) - 8/10 (between my 3rd-5th favorite movie of 2005)
3.Young Adult (2011) - 7.5-8/10 (my #3 movie of 2011)
4.Juno (2007) (either my 6th or 7th favorite movie of 2007)
5.Men, Women & Children (2014) (my #1 movie of 2014)
6.Labor Day (2013-2014) - 3/10 MAX (failure and/or boring. while i liked this on initial viewing it i could not even finish it upon a re-watch.)
p.s. for measure there have only been around 200 movies out of the 1,850+ total movies i have seen that i gave a 7.5-8/10 or higher to and only about 100 of those 200 are a 'solid 8/10' or higher and then about 54 out of those 100 are 9/10 or 10/10 status for me. so i don't hand out high ratings often unlike some people on this site who hand out 8's/9's/10's fairly commonly. to be clear i ultimately rate movies based on how interesting/entertaining they are for me and the further they get away from that then the lower the rating. i think boring is the worst crime a film can commit.
Besides, people go to movies for fantasy and imagination, not a docudrama about ordinary stuff they do every day.
i don't know about you but most(probably a large percentage) of those fantasy/CGI variations ain't nearly as interesting as Reitman's movies generally are.
but then again it could be a age thing as i am 35 years old (ill be 36 later this year) and think most of those movies (CGI/fantasy and the like) tend to be nothing special. but whatever it is, something about the general feel/tone/style of Reitman's movies i think are what grabs my attention.

I didn't get a chance to see it. This movie came and went like a dead leaf.
