After seeing Boom(2) I am having doubts about the show.
The two-part episode were more amusing than all the others, but the second part was way too predictable and unrealistic. A whole apartment blown up, every piece of wood lit by fire and Becket walks away without having a scratch? She walked away in Castles jacket, but the next moment has full clothing? Then, after spending one night at Castle's place she has all her own clothes again?? Also, after spending the night at his place, she cooked full breakfast in the morning; while in the previous episodes it became clear that she doesn't cook herself (much) but orders takeout. Now she's a 3 star chef suddenly?
This show tries to depict Becket as a strong woman, and it succeeded in it. But now it has gone to ridiculous heights. No matter what situation she and Castle are in, she always dominates, even when she is the target of a serial killer or has her house blown to pieces. How about chasing down a super intelligent (male) serial killer on 9 inch heels? Have you ever seen a detective on 9 inch heels? Well for Uber Amazone Becket it's less than a piece of cake.
Beckets reaction towards Castle is also way too uptight to be realistic. In several situations he either physically or verbally expressed his caring for her, while by description he's a true "ladies man". Almost all women that the show features comment about their "relationship", but Iron Becket states that it's "difficult". What exactly is difficult? She's single, he's single. Having another season where Castle hangs around Becket "just because he helps solving cases" devaluates the show.
There's no real tension between the two, more a sad display of Mr. Niceguy chasing the hotty.
I'm sure many will disagree with me on this, but I think there are a few that understand my point of view.
