I went to last Saturday's 10:30 show and was very impressed with this little less than 90 minute mind trip. The water performances and acrobatics was very impressive in which in this "no bad seat" theater. The friend that I went with is a Nevada resident, so we snagged two seats for less than $80!
I think from the previous yelpers responses, that I'm glad that I haven't seen "O" before I saw La Reve, because my standards may have been too high. I have seen KA and think that it's much better, but for the price of La Reve and that it's less than 90 minutes you can't go wrong.
