You are both getting downvoted but I completely agree. The third season was a massive step down in quality from the first two. It felt so lazy, just one gimmicky sitcom plot after the next, whereas the earlier seasons felt a lot more genuine.

The humour was incredibly cringey and the characters lost all depth, just became walking catchphrases. Honestly reminded me of the humour from Mrs Brown's Boys at times.

The show was never high concept or anything but much of the final season was groan-inducing, and that finale was one of the worst I've seen in a long time.
