I called them out on what appeared to be a pitch black or really dark room, but they panned the camera back to reveal that the room was really well lit (they were just using green screen tech to make it appear dark and moody).
with that said, the projector did well on the 3 main panels, demigorgon and the drop targets. the ramps, not so much due to their angle and how far the [white] stickers run up them.
they did have issues with the game itself in the first 5 minutes of streaming and it took them a few minutes (and glass off) to correct the issue. personally, I think that all of the cheapening out on the BOM is coming back to bite stern as the reveal didn't show the game in the best possible way. additionally, due to the fact that the game wasn't leveled correctly, ramp shots were rejected consistently and it just looked like the game was brutally hard (way too many SDTM drains by brian, jody and jack). why you wouldn't take an additional hour prior to streaming to make sure that everything was set up correctly and working the best that it could still baffles me.
finally, another thing that really stuck out was fit and finish. there wasn't any gap between the left panel and the center panel (which lowers to reveal the demigorgon), however there was about a 3/32" gap between the center and the right panel. that really cheapened it for me given the cost for these machines.
the theme integration appears to be right on the mark and code updates will only make that better. yes, there were a lot of placeholder animations but those that were complete were very well done. I especially liked the animation with the notepad with the numbered list and the 20-sided die roll to award you your reward.
as a few others have pointed out, there are a lot of shots on recent stern machines that come down and hit the top of the slings, rather than roll directly to your flippers which result in ricocheting into the out lanes a majority of the time.
