I did not want to watch this film as on paper it sounded awful and juvenile. I gave it a go and am pleased I did. As others have said, this is a mash between Groundhog Day and American Pie. A teenage boy is stuck living the same day over and over, every time he ejaculates he goes back to the start of the day to relive it. It sounds an awful film and there are some moments, such as him using his headteachers sandwich mayonnaise to help him masturbate to avoid being arrested, which bring the humour level down. However there are some genuinely funny laugh out loud moments. The ending is predictable, corny and slightly suspect. Would you really leave a boy in your daughters bedroom, especially if you walked in on them and she was just wearing a bra? There are some great performances especially by the lead I have never heard of before and Craig Roberts. Overall I would give this film a go. It sounds awful and juvenile but it quickly brings you in. You may not find all the humour funny or even tasteful, but there are some really funny moments. The Groundhog Day aspect of the film give it a twist that makes it stand out and above American Pie style films.
