Actually it is detention and apart from Groundhog Day, there are also hints of Breakfast Club here. A nice mixture if I may say so. I actually thought that I would just watch this - not expecting anything. Anything at all to be truthful. But then I got sucked in. The way it is told, the way the actors interact with each other (yes they're probably too old in real life to be pupils or in the detention/class they are portrayed in - suspend your disbelief, this isn't the first movie to cast people like that) - also the way the script works.
Never was I tired to see the same thing, because that did not actually happen. The main goal/target of the main character may be "simple" (minded), but if you only have a glimmer of romance in you, you will accept it for what it is. I can also feel for the teachers watching this. It's anything but easy to deal with a group like this. Yes you have cliches and some simple jokes too here. But overall you can feel the heart is in the right place. And you can also feel how much fun they had shooting this - no one is without fault or flaws. You won't identify with the main character all the time (especially when he's being extremely vile or at least stupid) ... but it wouldn't be a journey (or loop), if he (we?) didn't learn anything from it ...
