dS is such fun! Although I'll warn you that Fraser/Thatcher is definitely not central to the show; Thatcher isn't even in S1, and only shows up in about half the episodes of S2. (Then she gets turned into a walking neurosis in S3/4, but anyway...putting my rage about that away for the time being.) But the show is so much fun in other ways, and surprisingly nuanced for a buddy cop series. Fraser is just the most fascinating character--definitely both weird and competent, in that he often fights crime by licking the evidence to find out more about it, among other odd methods--and RayV and RayK are most entertaining in their long-sufferingness, and the ghost of Fraser's father provides endless entertainment, and there is (once you get past the first ten or so episodes, anyway) magical realism, outright absurdity, and much hilarity when comparing Canadian and American ways of doing, well, all kinds of things. There's also an intriguing strain of melancholy that runs through most of the series, particularly where Fraser is concerned. The last few episodes of S1 outright traumatized me, and I still can't listen to the Sarah McLachlan songs they used in them without wanting to cry, but damn, they were good.

Plus it doesn't hurt that Paul Gross is absolutely gorgeous.
