I'm just a bit concerned about the love triangle between Mike, Jenny and Rachel, which was kicked up a notch in "Shelf Life", when Rachel kissed Mike. Obviously they've been building up to this since the first episode and it wasn't a surprising turn of events, but the problem I have with it is that Jenny is awesome and I love her, and I don't want Mike to hurt her, or leave her for Rachel, or, worst of all, for her to have no reason to be on the show anymore. Additionally, I am yet to feel much chemistry between Mike and Rachel, despite the actors' best efforts; Patrick Adams sparks much more with Vanessa Ray's Jenny than with Meghan Markle, and the Mike/Jenny make-out scenes are sexy as hell.
As far as the writing of the storyline goes, I'm reasonably impressed. It's clear that Mike has strong feelings for both women: his relationship with Jenny has a complicated history but they know each other well and they love and respect each other. I also have no doubt that he's extremely attracted to Rachel and vice versa. Unfortunately I don't have any interest in seeing him and Rachel together. And because Jenny is so cool and lovely, it's rather difficult to sympathise with Rachel. If I liked the idea of Rachel and Mike, or if they had incredible sexual chemistry with each other, or if Jenny were a dickhead, it wouldn't matter that Mike is already spoken for. But none of those things are true, so the kiss instead makes Rachel look like kind of a jerk.
All that being said, I can't wait to see what happens next.
