Tonight: Frankenstein episode?

Is it just me, or did much of this feel like something blendered
together out of plot elements from other episodes (and are my husband
and I the only ones who thought Catherine's part came across like the
writers meant it for Sara but had to Find & Replace "Sara" with
"Catherine")? Also, I wonder if security for the lab's parking
structure is provided by the same folks who do security for County
General in Chicago. :) The winky-waggler confronting her at the end
was nicely menacing, though couldn't casting have got someone who
looked a LITTLE less like Alan Tudyk?

Still, Grissom & Hodges did get a good exchange of lines:
"What's our rule, Dave?"
"'It better be good'."
