Castle is one of those shows that you can pick up right where you left off, or even jump around and ditch watching in chronological order. It has an A+ cast, headlined by Stana Katic and Nathan Fillion, that welcomes newcomers warmly while containing a great dynamic. Even when relationships ensue (and ultimately fall apart), you can count on Castle’s inane theories, Beckett’s levelheadedness (the former and latter will merge and reach a good balance by the end of each episode), and a unique murder in each episode.
I’ve been watching Castle for most of my TV-watching life, but didn’t fully commit until the past year. By now, I’ve seen most episodes 2 or 3 times (especially the older ones), and can pinpoint my favorite guest stars and premises in a heartbeat. That being said, if you’re new to Castle and want to start at the beginning, these are the best of the old:
The Fifth Bullet
When an art dealer is gunned down in his gallery, Castle & Beckett discover that a bullet is inexplicably missing from the crime scene. The mystery is deepened by an amnesiac who witnessed the crime but can’t remember what he saw or even who he is.
A Deadly Game
In the first episode of a two-part “Castle” event, Castle and Beckett pursue a ruthless killer who, they discover, is part of a sinister, international conspiracy. Castle and Beckett are joined on the case by Sophia Conrad, a smart, sexy CIA operative who has a complicated past with Castle.
