Wow... and I thought it couldn't get worse after last week.
22 February 2012 | by (United States) – See all my reviews

Castle for some reason thinks that it has to keep outdoing itself, which unfortunately makes for horrible, schlocky television that is so overdone that I can barely watch it. My girlfriend and I were either laughing at how ridiculous these last two episodes were or seriously considering just turning it off. The only time I have ever felt like this about a show is when Stewie showed up on Bones season 4. Castle and Beckett didn't do much more than stand around and watch all the action for the entire episode. I like Castle, but the show needs to go back to its roots and stick to what it's good at... solving murders. This isn't 24. And they certainly shouldn't try to pack an entire season of that show into one episode of this one. Get back to the dead bodies, Castle. Now, we are going to go watch some Law and Order: Criminal Intent to detox.
