Some were actually good or do you remember the D&D movies so far?
I'm not arguing I just think they would make a better advertisement.
Just watched the cartoon series last year with my 11yo (I had seen much of it back when it first broadcast). I thought the animation was mediocre, the plots were quite variable, and they sure walked through a bunch of desert and swamps a lot. (Haven't seen them in ages, but my memories of the old Hobbit and LotR cartoon were significantly better). My son thought they were ok, but certainly not Ninjago, Power Rangers, Pokemon, Yugio, She-Ra, or random You-tuber level of rewatchable. I never saw any of the previous D&D movies.
That being said, I'm said Uni wasn't on one of the cards in the D&D secret lair that's coming out for MtG.
