"Homer the Whopper" didn't try anything new (could it have?), but I had fun with it all the same.

Jun 14, 2018 | Rating: B | Full Review…

The lackluster episodes may have felt tired, but even they could supply a genius bit here and there.

Oct 31, 2017 | Rating: 8.3/10 | Full Review…

The Greatest Story Ever D'ohed" wants to be subversive and make a larger point about religion and blah blah blah all faiths coming together blah blah blah, and ultimately fails.

Audience Reviews for The Simpsons: Season 21

  • Nov 26, 2016
    Season 21 continues the success the series found in season 20. Season 21 has a lot of creative concepts and even something more basic like Boy Meets Curl can deliver excellently thanks to solid humor.

    Funny at times but sometimes it isn't funny at all, show has been going on too long now i think, overall it is isn't too bad
