6. Entourage
While it started out as a fun, well-liked show — Entourage even received Golden Globe and Emmy nominations — its problems became magnified the longer it continued to run. The show focused on the day-to-day life of Vincent Chase, a young Hollywood actor, and his friends, whom he brought with him from New York City. The show was intended to give an insider’s view into celebrity lifestyles, as well as the highs and lows of the success that comes with show business.
The HBO series continued for eight seasons but “became a parody of itself,” The Huffington Post said. In fact, things became a little bit too perfect for the characters: Turtle accidentally became a millionaire, Vince was able to land every part, and Eric and Sloane reconnected (after he slept with her stepmom). According to the A.V. Club, the show’s ratings were down as much 25% in its seventh season.
