Ok, let me get this straight, badly made movie aside...
If I have this right, this was Shinzon's timeline:
First, he was created, sent to die in the dilithium mines, but somehow managed to rise from despised human slave to leader of the Remans, discovered a theoretical kind of radiation that conveniently kills everything it touches, has an enormous and practically invincible ship built, manages to infiltrate and exterminate the Romulan senate (The ENTIRE Romulan senate) and somehow manages to take over as Praetor.
THEN...
He reprograms a heretofore unknown prototype of Data that he managed to aquire from somewhere, rips it into six different peices, drops all these bits onto a populated planet under the assumption that not only will the locals not find them, but the Enterprise will somehow manage to spot the tiny signal of a positronic signiture from lightyears away through an electrical storm (the same one that prevented them from using their transporters to simply beam up the peices)and come to investigate, rescue, and reassemble this trojan horse so it can download all the information Shinzon really didn't need anyway since he had a ship with an improved cloaking device and an ultimate weapon.
All this just to lure the Enterpise there to he can transplant Picard's DNA into himself. (Aperently cloning it woudn't be enough)
Hmmm... Believable so far...
He then invites Picard and team down to the surface and instead of taking him by force and blowing up the Enterprise when they had the chance (What with the Enterprise's sheilds being down and all) he invites him to dinner where he once again passes up the oportunity to simply snatch Picard and take his DNA. No, instead he beams him out of his own ship later on and leaves him under the watchful eye of a single gaurd for a few minutes instead of simply starting the procedure and acts surprised when he is rescued, forcing him to put off destroying the Enterprise again until he can recapture Picard which he then tries at when their communications are knocked out in the rift (God forbid they radio to Starfleet they were attacked, aperently kidnapping a Starfleet Captain isn't enough to be a diplomatic foux-pas) where the Romulans end up turning on him with only two ships.
Huh.
Did I miss anything?
Is this really the plot of the movie?
