For the spots that the horizon levelling isn’t active (flat, non twisty etc) the vision looks just as good as some of those OurWorld and Theme Park Review POV videos. So ignoring Horizon levelling, The footage is smooth, clear, has decent sound, and is angled just right. If they did this with just a general go pro mount (as was mentioned a few pages back) then all the credit to them, and well done.
I actually quite like the horizon levelling, and honestly, non hardcore videophiles would be very happy with it, as has been the reaction on social media this morning.
