Most hated: The fourth one. I can accept that we need commercials to pay for the programming and don't mind putting up with two or three during a break, after all we gotta pee sometime. But four is way too many. I suggest that everyone boycot the fourth product - whatever it is, then maybe we'll have a reasonable number of commercials during a break.

BTW, have you noticed the Commercial Doppler Effect? - as you get closer to the end of the movie the commercial breaks get more frequent and get longer.
