I liked it but I was kind of surprised because making a musical of a show like Oz, you'd expect it to be either fantastic best episode ever, or jump the shark bad. Instead it was just okaish (IMO) rather than falling into either of those two extremes. Too bad there wasn't Keller singing to Beecher :P

And god yes, the writers overused Omar way too much in seasons 5 and 6, they seemed to be in love with the character's forced comic relief urgh.
