A group of unlikeable people. Not because they are bad or really even unlikeable but because their ability to communicate with each other and the people in their lives is astronomically bad. Seriously, in some scenes the characters are literally left speechless.
Sure, the misunderstandings create the drama, but eventually it reaches farcical levels.
The mystery/missing of the week is hit or miss, but pretty stereotypical and cliched. Absolutely, nothing new. Though, I can't say if its due to the seires' age or lazy writing. Probably the latter given everything else going on.
Season 1 is better than Season 2. In season 2, everyone got dumber. Not to mention bringing in the adversarial, annoying and controlling new boss just for even more cliched drama.
