It was over hyped tbh. It's a good film, but I don't think it deserved the attention it's been getting. Even BBC News have been reporting about it, although I guess it's because it will be on BBC One eventually.
The songs are catchy, the story is good, and there are some humourous moments. It's a feel good film, slightly cheesy, but nothing wrong with that. I enjoyed it.
I heard they're making a third film as well, it will apparently be a 'trilogy'.
