Re: I have an idea for the next Star Trek movie.
I don't think the general audience liking the new movies is a good argument against having TNG crossovers. The new movies both have spock prime in them and if the audience accepts that, they'll probably accept a TNG character showing up.
The reason audiences accept Spock (Nimoy) being there is because he is connected with the crew we are watching in action.
