The reviews below are excellent, so I can't add much value, except perhaps to add a comparison.

I also saw Cirque du Soleil's Mystere. It was a great show but :

the Blue Man Group was even better.
============================

I'd recommend the Blue Man Group for any age group, but older people (like, over 70) would have to be young-at-heart and willing to tolerate loud music. I don't know much about kids, but - I agree with an earlier review- they'd need an attention span that could cope with a full length performance.

I didn't sit in the splatter zone, but I still had a great time. I can't say whether it would be worth the extra bucks for a seat closer to the stage, but I can say that it was still worth seeing when I was about 20 rows back from the stage.

We went down to the theater at the Venetian around 1 am and bought our tickets for the show that night at 8pm. They were about $125.00 each, we sat in section 5, seats 25 &26. Got there at 7:30 and were very pleased with the seating. Perfect view. The show started off pretty weird and I started to worry we wasted our money. As it went on, it got funnier and more exciting. There were some cool surprises. Try not to find out too much about it, or you'll ruin it for yourself. Just go and have fun. Bring your camera so you can take pictures with them afterwards!

This show is impossible to explain. Lots of imagination went into this. Went with my husband (40s), 21-year old daughter and parents (in their 70's). Smiled or laughed the whole time. We were in the splatter zone - but they gave us plastic ponchos. No worries, everything came out clean. Just a precaution.

And who would have thought that a wall of tissue paper can be so intimidating?

This is a silly show. Entirely site gags. Not for the uptight or ultra-sophisticated. Great for kids old enough to sit there for the nearly 2 hours show, and can understand basic social interactions and expectations. Nothing obscene or questionable for youngsters - IMHO. Great music. Again, very, very silly.

Pay for the close-up seats - they were well worth it. After the show, they come out and you can get autographs or have your picture taken with them - with your own camera. Mom went up and said "hi handsome", and the blue man slipped his arm right around her to give her a big hug for the camera. Even had his arm around my curmugeon of a dad!! I never thought Dad would enjoy it, he's a stick in the mud sometimes, but since it didn't require his hearing aid for this, I think he had a great time. Dad smiled more at the show than he did at my wedding - but that gets into other issues I shouldn't address here! ;)

So - if you like silliness, GO! Have Fun! Be a kid for a couple hours! If not, stay in the room. We don't want to hang out with people who take themselves that seriously anyway!

I had always wanted to see the Blue Man Group, and on a recent trip to Las Vegas I had the opportunity to do so. The ticket price was average for the cheapest seats which I purchased (about $60-$70). When we arrived at the theatre we were informed they were closing the balcony and would be receiving a free upgrade. Basically we went form the upper back corner to the floor level maybe 15 rows from the stage! How many shows go through that hassle to make the experience better for you? If I went again I would pay for the upgraded seats, because many of the things they do would be missed from the back of the auditorium. It is difficult to explain what the Blue man do as it is a mix of music (percussion and rock mainly), lights, illusion, and comedy. In a city with little family entertainment, it is a show kids, teens, and adults all will enjoy. I highly recommend this show, so don't miss it!
