^I COMPLETELY disagree. OMG! There was chemistry all over the place, and in a, I thought, much deeper way. It wasn't just, "I think you're hot" flirtation, it was alot of, "we both KNOW where this is gonna go, and it's serious." I especially noticed it in Kate. When Castle was off spinning his theories, she had this look was this almost...adoration. More importantly, she let Rick see some of those looks. She's dropping little relationship hints everywhere, and Castle seems to be picking them up. I LOVED how she answered his question about her "number." Paraphrasing, but she basically says that guys in a relationship THINK they want to know, but they really don't. The look she gave him was definitely, I thought, sexy.
As for the writers not having fun...
The quips and general rhythm of this script seemed like a LOT of fun to write. There was alot of playfulness throughout, which I really liked.
I liked the Lanie & Esposito thing also, I'm glad they didn't just act like the breakup was not a big deal. We don't need it in every episode, but I enjoy these lighter more ensemble-like episodes as much as the more intense pieces.
I WILL say that what does stand out for me is that Castle is holding back. I can see it in Nathan's performance in that he has these moments where he's glowing in reaction, but then pulls back. Given the secret he's holding, I can see why he would. So, no, he isn't trying to kiss her, and isn't trying to push her. It's a bit of a role reversal to have Kate being the more flirtatious one, but given she's the one trying to knock down her walls, it makes sense.
I don't need them to be making out in the breakroom (at this point) to have something be Caskett. I like the sense of emotional progress in both characters, and it seems like it brings them closer together. I definitely DON'T feel that the show is over. For one, the characters continue to evolve. So many shows don't let that happen. Secondly, the progression is logical and has alot of room to keep going. I really think Marlowe follows the line of the characters' development, for the most part things add up. His first slip-up opinion was Beholder, but he's more than made up for it.
As for being a pessimist - you're allowed!
. I have no problem with them. Everyone doesn't view things the same way. It doesn't mean I'm gonna agree though.
