What are the best procedural episodes that go outside the box?
Maybe it's for production reasons, maybe certain casts or sets weren't available, or maybe the writers just wanted to try something different. The episode just does something unexpected, flips the script. Maybe there's a single focus on one character or maybe they travel to a different location that they never return to again. Maybe it's just more experimental in format. Some can be really poorly executed but some are genuinely good and fresh. What are your favorite episodes that break out of the formula of the show?
