Yeah, it totally jumped the shark when they ran off together. Overnight, they went from my two favourite characters to my two least favourite. I also became exhausted by the formulaic nature of Frasier's relationships, which is why my favourite episodes centred around other things. (For instance, in the Feydeau homage, it turns out that none of people involved are chasing Frasier and, as a result, he is humiliated.)
