Every time I read a summary of How to Be a Gentleman, I couldn't wrap my head around how it would work as a comedy. Indeed, the concept doesn't work and the pilot is a snoozer. I don't know if the show could work, but the writers never give it a chance. They give us a set of generic characters--the timid gentleman, the jock, the mean sister, the mean sister's weird husband--and that's about it. There's no indication of any future dynamics between the characters that would be worth watching, no interesting plots going ahead, nothing worth seeing.
Score: 6.5/10
