And yet you still have these repaints in your collection

(remember that these lists are meant to comprise of toys only from your own collection

)
I agree that the over-saturation of Bumblebees has spoiled the franchise and prevented other toys from seeing the light of day (e.g. DotM DLX Leadfoot, Soundwave & Quejack etc.), but I don't think that alone necessarily makes them terrible toys per se. I saw that HA Bumblebee w/ Backfire at Target yesterday... an utterly pointless and random looking repaint that does nothing for me. But it doesn't look like a flawed toy to me.
