Indeed. Retconing the film they're making a sequel to is usually a sure sign that the film makers: A) Don't like or understand the first film. B) Really want to be making a totally different film. And/or C) Have no idea what they're doing. Honestly I'm not surprised the studio messed with the final cut.
It boggles the mind just how many times they tried to recapture the magic of the first film. The results varied wildly from just plain mediocre to downright awful. Yes that includes the TV series. I'm sorry, I know it has a loyal following, but after watching about a dozen episodes, I just don't see it.
The short lived Raven spin-off looked like it had sort of the right idea, (never did watch it properly) but I gather the execution just fell flat.
