Whenever I've compared FLE to WS, I'm not talking about size or what they offer, I'm talking about what you see and whats surrounding you. FLE will pull you (well not you, but little kids) into the story, the sounds, and the feeling of the movie, very similar to how WS pulls you into the sights and sounds of different nations. WS is for an older generation while FLE will be for a younger one.
I will always prefer WS over FL any day.
You see, that is probably my biggest problem with the expansion. I'm still really excited about it but my problem with it is that it's directly aimed at little girls and little kids in general. This is exactly why Walt built Disneyland in the first place; so there can be a place where people of all ages can have fun, not just preteens. To be honest it seems sometimes like TWDC sees their parks as a place where they can steal money from parents of little kids and this expansion really isn't helping them with that. What they should really do is take a look at the plans and see what things they can do to change this to a land that everyone will love.
