Yeah, I have some big problems with it. First, it feels just like Ghost Galaxy+. It's better than Ghost Galaxy but feels VERY similar in terms of seeing a giant monster in space swiping at us via screens.
The lack of physical effects makes fans less likely to travel for it. If there's an amazing physical effect in an online ride-through, I usually think "wow, I need to see that in person!" If I see a screen on a ride-through, I assume that it looks similar to what I just experienced, seeing a thing on a screen. An entire series of pre-show rooms made up of nothing but characters appearing on screen means the only draw is the coaster itself. And if I'm a coaster-head, I'm heading to a park with a better coaster line-up than Epcot.
I actually think WDW's TOT would have been a better fit for Mission BO. It fits the park better as the park is now centered around stepping into franchises where DCA is still California-centric. The slower paced first elevator portion would have ensured proper show scenes instead of bouncing in front of the same one screen over and over. The 5th Dimension Room allows space for AA's and an adventure feeling as we flee from one lift to another through cross-fire and alien mayhem.
Plus, I also admit that I find the DCA version of Tower to be an overall improvement on the original, so its a best of both worlds for me. And the third win would be preserving Epcot's identity for a little bit longer.
