Re: NEMESIS: the good, and not so bad.
I hated the convenience of one major character's duplicate finding another major character's duplicate - completely by chance - without any explaination for it, whatsoever. Just happens to fit into Shinzon's plans because, you know, it's in the script.
I'm pretty sure B4 being deposited on Kolarus II was done by Shinzon. How else would he have reprogrammed him?
