I'm an official Rent-head. I think I've seen Rent 5 times? I still LOVE it! My mom and I used to be obsessed and listen to the album nonstop. I haven't listened to it in years, but I STILL know every single song! La Vie Boheme is my absolute favorite... with I'll Cover You and One Song Glory close behind. Heck, I love them all! And it didn't hurt that Manley Pope was Roger the first 2 times I saw it- YUM!
I saw The Lion King in LA my freshman year and I loved it! The little kid who played Simba had this annoying half-Southern half-Brooklyn accent that sounded totally fake and got to be really irritating whenever he sang. But the rest... WOW!
I saw Mamma Mia last winter. It was AMAZING! I wasn't expecting too much from it, but I absolutely adored it! It was totally original and the cast was amazing and it was just brilliant. It was sweet and sad and hilarious and just all around phenomenal. I LOVED it! I would love to see it again, too. And I'm a sucker for cheesy ABBA music, so that was also a bonus!
I saw two pretty awful musicals while I was in London a few years ago. It was pretty much torture for me and my little brother. Saturday Night Fever was nothing spectacular and Starlight Express completely bored me. I hated the whole rollerskating aspect, too. Just not my cup of tea.
Oh! and Cats! I saw Cats like 5 times when I was younger and I absolutely ADORED it! I haven't seen it since I was a child and everyone I know who saw it when they were adults hated it. I think its just one of those special childhood things to me.
