I enjoyed this movie quite a bit, although I do agree that the World's End part did drag a bit and was more than a little odd.

Honestly, I loved the scene where they got married in the middle of a fight while riding a Maelstrom. That was completely, unapologetically over-the-top and I loved it for that. The sheer ludicrous nature of it made it impossible for me not to be entertained.

It was good, I'd say. Toss up between that one and the first one. Generally well-written and thoroughly enjoyable.
