I was not too happy with it. I saw it as another cheap attempt by Disney to inject some "thrill" into their parks. M:S wasn't even that thrilling, anyway.
I've heard so many people saying how "thrilling" it is, but I didn't really find it nearly as thrilling as some may say. Really, the best way to describe it is Star Tours with a few launches. I wasn't expecting anything more than I got. Really, the reason why I was so excited about this ride was because it was the first attraction that I saw go from "start" to "finish." I saw it's entire "birth," you could say.
Anyway, back to the point. Another thing that I had a problem with was the story. What, are we going to Mars, are we just training to go to Mars, what? It seemed to be that we were just training for the occasion, but Mr. Sinise (did the character have a name?) occasionally said "First manned mission to mars." Plus, at the end, he makes a big deal out of you "succeding." And, if you were actually travelling to Mars, then why don't they hide the ride system more. I don't know, maybe I'm just an idiot.
So, it was a thrill ride, and thrill rides are all fun and good, but let me tell you about those. It seems that the main rides Disney used to do were slow moving audio-animatronic rides. Now, it seems to be that they're only doing thrill rides.
So, Disney's two main categories are slow moving audio-animatronic rides and thrill rides, and, when it comes down to it, I'd much rather ride the former than the latter. I'd rather see something amazing, awe-inspiring, touching and loveable than something that makes me scream.
So, all in all, I guess that I would be more pleased if, somehow, they mixed the best of both worlds. They could have built a huge space pavillion that educated you about the space program, and had a thrill ride to the side. I guess that I'll just always love Disney's bread and butter.
