Looks quite funny but I'm not a fan of how it is now the Alan and Chou films. The first one worked for me because they all worked together, all had their moments and just worked as a group. Now it just seems to be Alan at the front with Phil and Stu following him.
In the first they were all funny and all crazy in the situation in this one and the majority of the first Phil and Stu seem a lot more straight faced and mature but not due to character development, because Alan is the main funny guy.
I think its always been that way; Alan messes up and the others get entagled in his shenanigans and have to help him clear it up. The films have just gotten bolder, highlighting his actions more.
