I have seen all of the shows in Vegas.  Heard many great things about O so I left the best for last.  Oh boy was i disappointed!  First of all its very overated and over priced.  Second, there was no story line, a bunch of nothing.  The acrobats were OK.  Nothing to really make me say Wow. Honestly, i napped through some of the Show. From all the shows in Vegas, Le Reve is still my favorite.
