Criss Angel's live show beLIEve? reviews?

My family and I went to see Criss' live show beLIEve in las vegas about a month ago.. I honestly LOVED the show! But somehow the show still gets horrible reviews? I mean, I dont get it! He levatates like 4 ******* times, he does over 30 illusions, he's very humorous and entertaining! I honestly don't understand why this show gets so many HORRIBLE reviews?! Can someone tell me why he does? :/
