Great episode... I love original cast Star Trek stuff but Wrath of Khan is the only canon worthy piece. It is excellent and non-Star Trek fans see it too. I still well up when Spock dies, every time - that scene never loses it's power no matter how much I prepare myself. I liked the guest a lot too.
It's an easy call. Reeve's Superman is the definitive superman. I love the Lois shaken soda scene as well...Clark is better than the passive aggressiveness embedded in "midwest nice"..but it's totally a "midwest nice" move to subtly let people who underestimate or condescend to you know that you know exactly what they're doing and smile about it. I really like that this superman has a grace in his movements. MoS (and I'm guessing BVS) are obsessed with power...Supes takes off like a rocket and slams into anything and everything. Here Superman just rises smoothly and glides - it's far more powerful. After rewatching it this weekend the shift from young Clark (Jeff East) to Reeve's as Clark is slightly awkward. I wonder if they just couldn't make Reeve's seem a bit younger for that part of the film?
