Other mistake: When Capt. Picard is talking about a prisoner transfer, he says he will beam over to the Klingon Ship, then they can beam him down to the planet. He beams off the ship, and is then on the planet, but his transporter pattern (which should be Klingon red) is blue, the Starfleet pattern colour. He must have gone to the Klingon ship first, as his communicator is on his chest when he leaves the Enterprise, but gone when he lands on the planet, meaning someone, obviously the Klingons, took it off him. And don't say the Klingons gave the Enterprise the co-ordinates for Dr Soran's missile site, they're cleverer than that. (01:01:45)
Suggested correction: That's exactly what the Klingons did. They already had what they needed from Soran (the info to build a Trilithium missile and the decryption sequence to access it), and the very next thing they did was open fire on the Enterprise, intending to destroy it. They lose nothing at all by giving away the coordinates of Soran's site. This is confirmed in the movie when Picard goes to the Enterprise's transporter room and the operator says, 'receiving coordinates now, Sir.'
