I didn't grow up watching David Copperfield and never had much interest in magic shows. After last night, I am a believer! The whole show was amazing (yes, cheesy but well-aged cheese), and even better than the magic was David's showmanship and repartee with the audience. It was definitely entertaining if you let yourself enjoy and stop second-guessing.
Note: Bought our tickets from Vegas.com, which was ~$25 more than Tix4less prices even after I found a retailmenot discount. The site also assigned sub-optimal seats to us (since I booked pretty late). However, after asking, the theater box lady upgraded us to awesome seats (section 1 row C middle). David even did a couple tricks in the audience near us!
