Why yes, I am enamored with that collision of words, thank you for noticing!
Castle: Started out amusing, with Castle as the #9 most eligible bachelor in New York, and going to great lengths to hide rumors of a romantic link between he and Beckett, from Beckett. Once that ended though, the story got a little slow, and culminated in a fairly predictable pas de deux on a "oh so coincidental" set of dates (Castle with Ms. #3 and Beckett with Mr. June). The editing was sharp, cutting between Castle and Beckett trying to puzzle out the case to their respective uninterested dates, unfortunately the writing wasn't up to par, and so my interest was waning. The wrapup wasn't even that entertaining, since they apparently couldn't spring for a big black snake to at least give us that much of a sight gag. Castle jumping/shrieking when shot at was funny though, but not enough to make up for the episode. Only average tonight...you can do better!!!
Leverage: Great episode tonight, as they swing for the fences by bringing back Nate's nemesis (Sterling) and ex-wife (Maggie). Loved the tensions between Sterling and the Leverage team; starting with Elliot beating the crap out of him, then Hardison's frequent references to almost blowing him up, and finally with even Tara becoming fed up with him. The "I really hate that guy"/"Now you're part of the team" exchange between her and Elliot was such a well-written moment. Elliott really shone in the episode too, taking over once Nate and Maggie were taken hostage. Sterling managing to get yet another promotion off of the hard work of Team Leverage was nice bit, although he may have earned it with his performance when Parker needed a distraction. Another great episode, and I can't wait to see what comes next week.
Thursday comedies were reruns, so enjoy the final Dollhouse tonight (if you're into such things), and I'll be working on doing a season's worth of catching up on it and some final thoughts about yet another entry in "Joss Whedon's Case Against Fox".
