Being funny is hard. Being funny for two hours, is very hard. That’s the challenge laid at the feet of Trainwreck from the start and, like most Judd Apatow films, it is probably around half an hour too long. However, it does manage to be funny. A lot of which is due to a star making performance from Amy Schumer, who is also the first person to write a film that Apatow directed who is not called Judd Apatow.
