I've never seen Cable Guy, but I did wonder if they were supposed to be in the same vein.
All I can tell you is that O&R was the biggest piece of crap I've seen in a long time - worse than Rachel Getting Married and THAT was awful!
Saw it w/ V., Mandy and Ryan and all of us regretted not walking out. We were all thinking about it but didn't act. Truly - don't waste your money or time.
