Fan Favorite Episode #1
3 November 2013 | by (Kurunegala, Srilanka) – See all my reviews

This felt like it was a tribute the uber-faithful fans who kept the show going during its turbulent first 2 yrs..until "Still" came along in S5. I've watched my share of black & white 50's & 60's movies as my grandpa was a movie director of sorts & hence his movie craze kind of rubbed off me, and I've got to say that for a TV procedural with one of the lowest budgets on ABC, Castle got everything pretty much spot on, from the accents to the props to those fantastic dresses that Kate & Lanie wore. Excellent plot, superb acting. And even better was the love story unfolding. Stana was just drop dead gorgeous in that blue dress! And THAT kiss at the end..the Castle fandom literally exploded! Kudos to Tamala Jones..who knew she has such great pipes? She should sing more often.
