11. My Big Fat Greek Life (CBS, 2003)
Starred: Nia Vardalos, Steven Eckholdt, Lainie Kazan, Louis Mandylor, Michael Constantine, Andrea Martin, Gia Carides
How many series based off of a successful film last? More importantly, how many of them are actually good? Audiences loved Nia Vardalos' romantic comedy My Big Fat Greek Wedding but were unsurprisingly not up for a whole series dedicated to the Ian character's (renamed Thomas on the show) stranger-in-a-strange land misadventures amongst his Greek wife's stereotypical Greek relatives. Apparently this terrible idea was Nia Vardalos' call, which explains why Hollywood hasn't seen much of her since.
