I think that after taking artistic risks and with a beautiful artistic design aesthetically in TMP and attempting to push ST beyond what it had been, the subsequent scaling back of things in TWOK feels sort of cheap. Also, the Moby Dick homages feel kind of badly written. I prefer III, and especially IV, over TWOK. III for me and IV are the only movies that recapture the feeling of a TOS episode. Also, Shatner's TJ Hooker perm kinda ruins films II - V for me.
