If that's the criteria, then TF Prime is easily the worst TF line supported by media, both TFP and TFPBH. The toys are largely unsatisfying, overpriced, and underbaked. I'm displeased with well over half the product in the line, it's the US line I've bought the least of since G2, far and away. Up until DOTM, I bought a large percentage of every line from BW until that line, DOTM's product downshifted me to being considerably more disinterested, but it was TFP that finally really killed it, I'm now extremely cautious with my purchases. And the media support is middling at best.If you guys love almost all of the Energon Decepticons,then it's not the WORST TF toy line sponsored by a media cartoon/movie. The WORST title should belomg to the TF toy line that had the LEAST amount of toys you liked ,not 50%.
Armada would be my runner-up, I bought nearly everything but looking back there's a lot of terrible there. The show was kinda dumb but sold the product well, which made the lackluster product that much more disappointing.
Energon would be third place, a malaise permeates the line, nothing's *terrible* but not much is great either, everything feels chunky and tired. The show did a bad job selling the product.
DOTM would make my fourth place, the movie is violent and hateful, but the toy line is just fraught with uninspired designs and budget cutbacks, this was an area where less toys got bought, yet at the same time there were more ideas.
PCC would be my fifth place if it had media support, but it didn't.
