Speaking of films, I went off to watch "Scooby Doo 2" at the cinema this afternoon, which I enjoyed. Overall, it's a fun film, and I'd definitely recommend it to anyone who liked the first one.
There are different ways to handle film sequels. You want to be similar to the original, without being a complete copy. I think "Toy Story 2" was a great example of how to do it right, whereas "Austin Powers 2" was just a rehash of the first one. Scooby Doo 2 did it well; the characters are familiar, but this story is different to the first film.
Speaking of similarities, there's an impressive amount of continuity in here with the old cartoon series, but it's handled well; you don't need to have seen the original episodes to understand anything. For instance, I'm pretty sure that a couple of the things they mention in the film (e.g. Shaggy's real name) only came up in "A pup named Scooby Doo". So, that certainly implies that the people who made this have done their homework.
Mind you, when they showed fans in the film, it was a bit like the first half-hour of "Galaxy Quest"; uncomfortably true to life. I guess there are levels of cult-following behaviour, and it's only a problem when people start defining themselves in terms of their obsession.
As for the jokes, I wouldn't exactly say that they worked on multiple levels. But there was some variety there. Listening to other people in the cinema with me, the things that made me laugh ("To museums!") were different from the things that made the young children laugh (e.g. fart jokes). So, I think there's something for everyone there.
There were some interesting scenes when they played with the group dynamics a bit (e.g. Daphne and Velma working as a pair), and there was one scene that I found genuinely moving.
In the spirit of "Do men prefer Buffy or Willow?", I definitely prefer Velma to Daphne. Although I wasn't too keen on the shiny outfit. And Velma and Daphne both beat Dale Arden (from Flash Gordon) any day of the week.
Speaking of Buffy, it was great to see Oz turning up here. More generally (as with the first film), the casting was spot-on.
As for the mystery, I won't give away the ending. All I'll say is that I only figured out part of it.
So, all in all, two thumbs up! There is something after the end credits, but it's only worth staying for if you intend to play the computer game.
