I think the product description given is a little unfair. There is quite a bit more to this comedy than one can generally expect from your run of the mill romcoms these days.
Sure, there aren't any sudden twists to the plot, but from a guys point of view, this romcom actually does have some of the 'com' element too it rather than just the sappy rom stuff.
There are laugh-out-loud bits to it and even my wife who was desperately sick while watching it (not because of the film) managed to laugh out loud as well.
It also picks up some serious issues in regards to the consequences of being stupid i.e 'sleeping' with a kiki dancer at your stag party.
So if you're a guy and your girl is really wanting to watch a romcom with you and you would possibly rather spend an hour slitting your wrists, then this is going to be a good choice for you. She will enjoy it, you will laugh at some bits and also not throw up from exceess sappiness.
And if you're a girl and want a fun girlies night in then this will get you all giggling a plenty.
