I'm also of the camp that prefers original stories. MCC and MTI were fun experiments but now they've been there, done that and it's now time to move on.
...however were they to do another story, Robin Hood would be at the bottom of the list since it was already done on the Lynn Redgrave version of The Muppet Show.
...so along those lines, i wouldn't mind maybe one or at most two shows a season in a television series were they put on a "play" of a classic story like they did in that TMS episode. But with movies, they come out so infrequently that i'd rather the team put their time, money, and effort into something original than blow it all on a "retelling" and then have to wait another few years for the next movie.
