After a few episodes, they begin increasingly repeating the same stuff they've already repeated 3 times over, the same film clips, the same script, the same everything. It started out as an interesting cold case. If they'd just progressed it naturally with limited review it would have been great. Now I'm watching season 2, episode 2, and it is almost an exact copy of season 2 episode 1, which was a complete review of season 1. They don't even bother to change the clips - it's the same video, the same suspects, the same everything. I had to stop it to see if I was watching the same thing over, but I wasn't.
