Yeah, that 45 minute “drift” through the ”cloud” sequence was a complete waste of celluloid; I have to fast forward through the majority of that snooze fest (about as boring as the highly overrated 2001: A Space Odyssey).I've come to appreciate it more with (my) age, though it was still a hard slog when I watched it a few months back. But it's probably the only Trek movie you could call pure SF.
