I’ve not read the books and after watching part 1 I was left confused why everyone loved them. I didn’t dislike the film, it was just fine, but it didn’t get me excited for part 2. Sure I’d watch it, but if it were delayed or cancelled I wouldn’t have minded.
For me part 2 is everything I wanted in a film. I would nearly go so far to tell someone unsure about the films to skip part 1 and just watch part 2. In reality I think doing that would be a bad idea, but part 2 is better than part 1 in nearly every way.
#2 because it allows you to later give them a mustache (#1), which is funny but the toaster isn’t amused.
