Yea, that was strange. That opening was too good not to see again.
It was entertaining start to finish. I really liked the way they captured the look of a typical sexy woman wrestler, and the typical not so sexy woman wrestler. They looked like realistic, attractive women, yet eccentric, like the kind you'd see in a wrestling ring in the 80's. Hell, anyone who wrestles for a living is a little crazy, even now. The ring is no joke. I took a few bumps once, and it doesn't take much to get fucked up.
If you haven't watched the documentary about the actual GLOW wrestling in the 80's, check it out, it's great.
