Season 16, Season 19, Season 20, Season 22 without any sort of a memory challenge and the whole finale literally being one sided. Only Season 20 had Dave and Rachel sort of falling behind at one point, but it was only for about 5 minutes and then they miraculously gained their lead again and won. Those were the few bad ones that I could really remember.
Season 18 had no memory challenge but the sudden catching up by Kisha and Jen is a shocker so... it was kind of interesting. But still, boring. Season 15 had no memory challenge but the teams position changed like nobody's business and it was fun to watch. Season 13 was sort of one sided too, it was a little boring but the fact that there's a memory challenge made up for it. Season 17 was one sided too.. but again, the fact that there's kind of a cool memory challenge made up for it as well.
Post Allstars, I really liked TAR 12, TAR 14, TAR 15 and TAR 21 finale episodes. <3
Pre-allstars I like TAR 2, TAR 3, TAR 5, TAR 7 and TAR 8.
The worst of them all? I think TAR 6. Still can't believe that eating a whole pizza was actually part of a finale task.
