Answer: According to the IMDB, there are currently 10 different series (with an 11th premiering in 2006). And, as far as I can tell, there have been only two theatrically released movies. All of the series, with the exception of the first one (that premiered back in '93) are spin-offs of the original, and they all share similar plot lines, characters, etc.
