I thought they tried to have too many themes. I was hoping at the start it would all be about *spaceology*
Linehan appears to be trying to do a Seinfeld with his recent stuff, and failing miserably. You could argue the whole male masseuse story was lifted from the Seinfeld episode "The Note". George: "I think it moved".
The arse kiss was just thrown out of nowhere with no pre-setup or any context made. It happened just before an ad break so you had a whole 3-4 mins to be thinking, "WTF? Where the hell did that come from?" It wasn't until a long way into the "trial" it was given some sort of plausable explanation, i.e. a masseuse taking pride in a massage well done, and even then it was half hidden behind the various similies of the word "bum" by Roy. Up until then we were left to thinking it was an actual sexual assault, why? what precontext was there for this? They didn't even resolve the trial, just a slow hand clap?!
