It's interesting to read peoples justificat... I mean explanations as to why they collect what they do :p
I'll admit I thought about getting a set of Movie Autobots in the most kick-ass model they came in yet still to a relative scale. Who'd want a BB that was bigger than Prime? (Even if it might be awesome) Be it Prime from the 3rd movie, Ironhide from the 1st, Ratchet from the 2nd etc.
In the end I didn't, because collecting for me is about the association with character. As Sky Shadow pointed out, with BW, if the show character had a not-so-good toy, you were stuck with it becuase of the way the line was structured, but it was still that character none the less. Blackarachnia for example, I couldn't wait to get the Takara 10th Ann version just because it looked much closer to the show, yet I'll still keep the original Hasbro version. Patience is a virtue I guess.
For me and the movie toys, I can only hope one day they put out an 'Ultimate' line. No repaints, just the best version of each Movie character. Likelyhood of Hasbro doing this... Hahahaha, as if.
