Watched a POV, I think it looks like like a good fun ride. The projections certainly give the ride a very unique environment. There are some moments that just flow nicely but really make me wonder how the effects were done. I really don't understand why people are against this ride. Seems to be an update to the classic Disney dark ride to me. I get people feel nostalgia for the GMR. But lets face it, that ride was outdated. Sure, I wish MMRR didn't replace a ride and GMR was still around just for the pure fact that DHS needs attractions. But to say this is not a worthy replacement for the GMR really baffles me. I think it fits perfectly in the Chinese theater aesthetic from what I have seen and it is something truly unique. To each their own I guess....
On a side note, I can't believe people aren't talking more about the pre-show. It certainly wasn't what I was expecting.
Final note, based on the POV I watched it looks like there are still some timing issues to be worked out.
