It is a fine episode. I watched it for the first time last Sunday. Many things made it an enjoyable and memorable experience for me. I thought Spock's curious behavior was intriguing, as was Pon farr altogether. Finally seeing Vulcan was a treat too.
I had a couple of verbal outbursts during the episode; once at T'Pring when she chose Kirk as her champion and then again at McCoy when the fight was over. "CPR! CPR! CPR!"
The fact that Vulcans didn't choose their mates by any logical means didn't bother me. My only qualm with the episode was Kirk's reasoning for accepting the role of T'Pring's Champion. It felt, to me, less like something Kirk chose to do and more like something the writer forced him to do.
It's one of my favorite episodes as well.
