Thought this week's episode was very poor.
What really annoyed me about it was the Marshall storyline. It's a typical HIMYM episode where they introduce a concept that everyone's on board with (even though we've never heard about it before, but ok), the approval stamp thingy, and the whole episode will revolve around this. Marshall's storyline in it was ridiculous, badly written, and the 'twist' was stupid: it's a sitcom, so I'm not asking for realistic situations all around (I wasn't disturbed by the Barney/Robin storyline in this one where they vet strip clubs, it's not a situation that would ever arise like that, but I understand the comedic value of the situation so ok), but this was just pushing it, no way a guy would come into a room, take pictures of an 'entire case strategy' (sic) in a glass cubicle and be able to use it against a law firm. Or, for that matter, would a law firm leave its entire case company accessible to an outsider. That was just plain silly, and apparently they're going to milk that storyline. As for the Ted/Lily parts of the episode, I found them typically Ted boring in the 'I find out I'm not who I thought I was but in fact I'm still a great guy', very predictable and not even that funny.
As for the Robin/Barney conclusion, of course we knew it was coming, but it's still really annoying.
