I must be missing something.  She seems so *fake*. (The character – not the actress).

If she's ever in a mood it's a cute one, and everything she does comes across as a privileged prima donna. Her jeans are tame, she never has a bad hair day, every movement falls into a charming pose suitable for framing.  She's clearly living in an "I'm smarter than daddy and richer than Croesus" world.  It's too sweet.  Makes the show hard to watch.

I'm not saying Alexis should channel RoseAnne's heinous slag of an offspring, but maybe Mel Gibson's daughter in What Women Want (Ashley Johnson)?  I'm just sayin – she's an insanely beautiful girl, but we want to watch her be human. 

It's only enabled by "Grandma," played by a theatrical legend. I'd welcome a relationship more like Gilmore Girls (early seasons), where Grandma fought to leave her shell and Rory fought to find one. The Castle women are in stasis – too happy where they are.  There's no tension. It's too pretty. You could leave it out entirely and all you'd miss are cheesecake shots and lame, pointless "banter" to frame Castle as an even more successful hero.

I think somebody is missing a chance to play with Alexis and Grandma. It's a shame for all – Alexis is in a great spot for a spin-off, but who wants to watch the perfect whitebread life continue its perfect ascent?

Friends was about their collective *failures*. Clueless made fun of itself (classic: AS picks herself up off of the ground after being "mugged" and whines about her shoes; epilog commented about this "is not Kentucky").  The bottom line: Castle (and, by extension, Alexis) takes itself way too seriously.
