there are two things that really grind my gears (not the autobot!)
1. All the @$&!#*% repaints! I'm a completest collector and I really hate spending three four or five times the money on the same damn figure!!!!! At least retool the head or weapon or something (I feel like I'm being bent over and someone hid the lube)
2. Electronic transformers with really REALLY poorly place sound buttons! for example - Energon Scorponok and ROTF Leader Prime! I was so close to throwing prime against the wall when I was learning to transform him that even now it bothers me to hear "My name... is Optimus Prime"
Sorry to rant but it does feel much better to get that off my chest!
