If I could only review seasons 1-3 I'd give them a solid 10, the writing is great and every actor does really well with the script. Unfortunately, seasons 4 and 5 exist. Season 4 is pretty bad, each episode centres around a character, so we never really see the whole family together. This was done because of scheduling issues, but it ruins the season.

This isn't the only issue, however. Before the release of season 5, Netflix released a remixed version of season 4, which was much closer to the original 3 seasons. Instead of there being an episode for each character, scenes from the previous episodes are put in a different order. This does make the season better, but it doesn't save it from the bad writing and weird plot.

Season 5 is a lot better, however. The writing is funnier and the characters act much closer to how they acted originally. It still isn't up to the same level of greatness that seasons 1-3 were, but it's a huge improvement over season 4.

If you want to get into this show, watch seasons 1-3, and only watch after that if you absolutely must.
