A 2 parter doesn't have to have a bigger consequence than the last one.
21 February 2012 | by (Canada) – See all my reviews

Yes this contains spoilers. Nathan Fillion can do no wrong, and I love the show, but this one missed the mark in the end a bit. Maybe I need to watch the "Pandora" episode again but the ending fell a bit flat when I guessed who the traitor was just because they gave no clues to hint at who it was. Again I need to watch the first episode again in case there was a throw away line that hinted toward the real culprit.

The pacing was excellent and really pushed the story forward but When Beals' character (Sophia) all of a sudden is the double agent, she's Russian, and then reveals she knows something about Castle's mystery father? A little too much shoe horned into a minute of dialogue. By Beals/Sophia being the antagonist anything she said is now suspect and adds to the trouble of the shoe horned information at the end. "Castle and Beckett save the world" would be better as a joke than part of their characters history, they're detectives not super heroes.

Yes the sexual tension is a large component of the draw but it is wearing a little thin, they don't have to jump into bed right away, but a date episode where they have to deal with each other when they are not brought together by a murder could be an interesting episode. Beckett's unavailability for a relationship is a great tool, but if you go so many episodes without at least mentioning any progress made on the subject it becomes weak as a singular obstacle. I can see that Sophia's comments to Beckett about "Ruining their relationships spark by having sex" were meant to reinforce Beckett's trepidation with giving into her feelings for Castle, but because it came from the antagonist it means almost nothing and seemed more like the writers were asking the audience to hold on for the rest of the season before Kate admits she remembers that Castle said "I love you" in the season 3 finale.

This Season 4 has been a lot of fun, but the Linchpin here is that Castle and Beckett are getting left in the friend zone. The real Linchpin was a powerful family from China that could ruin the U.S. economy if their daughter is shot is a great premise but the plot of a double episode shouldn't be a tag-line, a little more could have made the ending a little less rocky.

I love the show and I will keep watching, but please, sometimes less is more, with regards to the plot, and appetizers are better than a tiny taste before dinner, with regards to Castle and Beckett.
