The app isn't that revolutionary -- we've seen virtual environments before from Netflix and others, and the handful of VR-specific content (just 25 examples at first) probably won't have you buying Gear VR just for this. All the same, it's still a big step toward legitimizing VR. You now have a better reason to don that headgear on a regular basis -- you don't have to wait for sports events or other special occasions to see something new, even if it's not VR in the truest sense.
