Spiner himself explained,
One of the ideas that John Logan and I had about what the next film would have been was a Justice League of Star Trek. Something would bring all the great Star Trek villains together, from Khan to Shinzon, and Picard is the only person who could stop them and he actually has to go through time and pluck out the people he needs to help him. He goes back to the moment before Data blows up and takes him back to get Kirk and Spock, and go even further back and get Scott Bakula’s character, Archer.
I can’t imagine it would have been good, but boy do I wish I existed in a universe where this movie had been made.
Same! I’ve always considered time travel to be a “plot cheat code” because it allows writers to do whatever they want. This works out ok sometimes but other times it just makes for bizarre stories that defy belief. This would definitely be the latter kind!
I enjoy ST largely because it’s believable (in a broad strokes ignore the details kind of way) so far-fetched stories don’t do it for me as much. Time travel is firmly in “never gonna happen” territory.
