I rode Rise of the Resistance this morning. It is phenomenal. Really ambitious attraction that lives up to the hype. Crazy combination of ride systems, pre-shows, huge sets, and great animatronics. There's a ton going on -- it is quite literally sensory overload in the best way. Try not to watch the videos if you can resist, the surprises are worth experiencing for the first time in person. I was really impressed, as was everyone else I talked to who rode it.
There are several experiences totaling about 15 minutes. It's pretty uniquely laid out, and the "ride" is only one portion of it.
