Criss Chros – 30 Rock
In the episode “Idiots Are People Two!” Chris Chros made his first appearance on the show. People thought Liz Lemon, who James Marden played, could do better. Well, they weren’t entirely wrong. The protagonist was a hot dog vendor who studied ethnomusicology in college. There was a lot of backlash on Twitter when he joined the cast. On the other hand, fans thought it was good to pair her with someone who wasn’t overly ambitious.

Marc Brendanawicz – Parks And Recreation
It’s no secret that Leslie Knope of Parks and Recreation has a large fan base. This is most likely why they despised Mark Brendanawicz, who appeared on the show for the first two seasons. The city planner was brought to life by Paul Schneider. Despite Leslie’s strong feelings for him, he dismissed her and went on to date her best friend! Many fans were relieved when the character was killed off after the second season. According to the actor, he left due to “creative differences” about how his character should be written.
