You can't really have any appreciation for the movie at all without watching the series. It's like watching the season finale to a show you've never seen. Nothing has any context. Though to be fair, it wasn't the best movie. It wasn't bad, it just had to rush things, and none of those things would make any sense without context. They were bad enough *with* context. If you enjoyed the characters at all and felt you'd like them more if you had a better vehicle for their appreciation, then you should check out the show.
