Cool game, I'd recommend it for anyone who likes either show.
The obligatory investigation/interrogation systems aren't the most elegant but they get the job done. While the overarching case is interesting it doesn't really leave you with any mind-bending twists or big logic puzzles, which is fine but it leaves the game feeling a bit predictable. At times it feels like the game is just quizzing you to check if you've paid any attention to what's going on, which would be less annoying if they let you check your keywords during dialogue.
The biggest flaw I felt was the ranking system at the end of each chapter. Mystery adventure games have very little replay value by design, unless your mysteries are artificially generated or randomized in some fashion the outcome of the narrative remains constant, so why grade the player on their performance?

oh yeah, the bomb defusal minigame was cool, even though I hated playing it
