Yeah, actually.
I'm not a huge MJ fan (but its not like I hate him or strongly dislike, and I do like his music!), but the technical theatre stuff was awesome!
My dad and I kept commenting on how MJ didn't seem 50 at all! He was still as quick and sharp as ever.
I watched it mostly because my dad got it as a gift from my mom and wanted to watch it, but I was surprised at how much I enjoyed it.
(It helped that there were a TON of Haunted Mansion references in the Thriller section

)
