“I can't imagine it would have been good, but boy do I wish I existed in a universe where this movie had been made.” — This is the perfect reaction and I cannot improve on it in any way.
I like Star Trek V. I've never really understood why people say TMP is the most like TOS, I think it has a pretty significantly different tone, but V really just feels like a middle of the road TOS episode with a way bigger budget, and I think it's a bunch of fun.
