Meh, so much complaining.
It was a fairly filler episode, so not much to say about it either way. Fun enough but certainly not very memorable - "assembled from spare parts" seems a decent way to describe it. I'm just glad it didn't end up being the Bigfoot hunter, and I can keep up my streak of "I haven't been able to identify the killer because of recognizing him/her from elsewhere" that other people seem to run into so often.
Also, I'm not sure how I would have felt if Jiminy Cricket (or even better, Kaiden Alenko) was the killer.
Though - now they've had Garrus and Kaiden, who's up for having Miranda or Anderson or - even better! - FemShep guest star?
(Why yes, I have been playing a lot of Mass Effect lately, why do you ask?)
Also, Castle and Beckett in bed together... "D'aww...."
