I wouldn't really recommend this unless you're a real diehard Elvis fan.
The show is basically a a history of Elvis and highlights the biggest moments in his life (my favorite is the 'Can't Help Falling in Love' performance) through video clips, dancing, and song.
I have to admit this Cirque show really lacks the "soleil" you would expect. Not so much acrobatics or theatrics compared to Ka or O. Although I did enjoy the "comic book" performance.
The venue is nice with very comfortable "loveseat" type seating in the front rows.
If you just wanna enjoy Elvis's hits, then this is the show for you.
