I hadn't caught a review of it, but sounds like an easy enough pass... at least till they inevitably repaint it a billion times.
Actually I'm not so sure BB units will interest me like their R2's have. The 3PO's are cool but they're not interesting me the same either, so I am not sure how I'll feel about BB units of all colors. The protocols definitely left me sorta meh, and while I'll want some I certainly don't have that need to pair parts up at an absurd level.
I hear they're a bear to make too, in a crowd at least.
But yeah, BB8 didn't strike me as too cool anyway... I have a couple that work fine by me, and don't need another, but I like the idea of the weight in the bottom keeping it upright. That's a nice innovation. Attachments like his torch arm would've been neat. Like you said about Chopper, who if they repainted I'd rebuy happily again and again, that's a tough act to follow because that was easily the best action figure of the year outside of the Black Series Rogue One figures in my mind. And it was easily as good as they were.
