Also, I would have preferred a Picard clone that had all of Picard's memories and experiences, but was programmed with Romulan dogma and politics. Now THAT would have been an interesting movie. Imagine the conversation as Picard tries to reason with his Romulan-cloned self.
But the "clone with the memories of the original" trope is one of the silliest cliches of clone stories in fiction.
NEM is already a silly cliche of TWOK, and it didn't work.
There's absolutely no sensible reason why a clone would have the original's knowledge or memory. Those things aren't genetic. Sure, some stories rationalize it by assuming mind scans and downloads or katra transfers or whatever, but how the heck could the Romulans have scanned Picard's mind without him knowing about it?
Really? There's ABSOLUTELY no way of coming up with a Star Trekkie plausible way to do this? None whatsoever? None?
