For something which purports to be depicting situations that the audience can relate to, I can honestly say I do not know anyone who is anything like any of the female characters presented. Admittedly, the male characters are exactly like many men that everyone has come across at some point.
By the time all the main characters (although, using the word characters is a little misleading, as it suggests they are part of some actual narrative) have been introduced, you know exactly how the film is going to end, roughly two hours later. Nothing happens within this time to make you think otherwise. In fact, not a lot happens within this time at all. As mentioned earlier, it suffers from a severe lack of plot.
The only upside of this film is Bradley Cooper. Unfortunately, this is just due to his presence in the film, and not due to any particular contribution. This is a little harsh though, as nooone has much acting to do. This must have been the easiest pay packet that any of them have ever received.
There are plenty of much smarter rom-coms around. Watch them instead.
Although not all of them feature Bradley Cooper...
