For over 15 full seasons, Grey’s Anatomy has been taking fans on a wild ride of highs and lows, great romances, and tragic goodbyes — and right now there is still no word on when the show will be ending. Each season has offered something new to fans, but it all circles back to some central characters and major storylines, and after so many seasons it isn’t surprising that not every season has been spectacular. It is hard to remember everything that has happened at Seattle Grace/ Seattle Grace Mercy West/Grey Sloan Memorial Hospital over the years, so take a look back at all of the seasons so far ranked from worst to best:
16. Season Four
Season four of Grey’s Anatomy ran from September 27, 2007 to May 22, 2008 and marked the beginning of major cast changes for the series. Although the season provided some very memorable episodes and included the introduction of Meredith’s half-sister Lexie, it lands at the last spot on this list because the writer’s strike that year cut the season short. Along with some of the good things from the season such as Derek and Meredith getting back together and Meredith’s grand gesture of building the candle house, it also included the cringe-worthy George and Izzie hookup. Season four of Grey’s wasn’t completely awful but ultimately fans will never know how much better or worse it would have because it never had a full episode slate like the rest of the seasons.
