The movie arrangement is based on a common opinion that the even-numbered Trek movies are the best Trek movies. I'm not really on board with dividing the movies up like that, but hey, I wanted these two to bond over Star Trekkery, and BOND THEY DID.
I mean, they've bonded. They're not interested in watching Bond movies. Well, maybe Justin is, but it's a pretty safe bet that Susan wouldn't be particularly fond of James Bond.
Confession: I've yet to actually see all of Star Trek V. From what I've seen and know of it, I don't think watching it all the way through would improve my opinion of it, but I suppose it's possible.
