Yeah, it's basically what Nimoy did in TSFS: He deliberately made the Excelsior Captain and the Grissom Captain either smug or indecisive just to make it clear how awesome the Enterprise crew are.
That's too bad. I like my stuff just a bit less hokey. What if in GEN, a competent officer was still overtaxed and Kirk has to step in to assist? He's still needed, and maybe moreso, since he's not replacing someone clearly a putz, but someone who's competent, but even so, still needs some Kirk?
When I become a scriptwriter I'll do it right.
