First of all, the title is a bit misleading. I was thinking it was going to be something like CSI or Criminal Minds but that's much more of a drama show around character's personnal lives. So don't expect it to be a canadian CSI because it's clearly not!
Another thing that bothered me a bit is that CBC kind of ruined it by pushing too much the "canadian multiculturalism" thing. Not that I dislike multiculturalism but when it feel forced (like in this show) it gives a "fake" vibe to the show as a whole.
All in all, it's not bad. If you like lots of drama with a little bit of crime investigation that might be OK for you! Or if your girlfriend likes drama and you like CSI-like stuff, that might be a good deal for you both ;)
