While I do like this show, it has a few things that bother me. Some guests are on far too often, like Doug Benson. And Chris needs to stop laughing so much at his own jokes. On the plus side, I've discovered a lot of comedians I hadn't heard of before through the show (That's one of the reasons I think they need a better variety). The comedians are almost always a funny mix with only a handful of exceptions, and the three that appear always seem to be a good mix of talent that compliment each other's styles well.
This is the weak link in the Chicago series. The main reason is Dr. Halstead - an awful character, a doctor more concerned with his own ego than his patient's wishes, a man who pushes what he wants onto others whether they are receptive or not (breaking the law at times while doing it), a man who went after a pregnant widow who was still in mourning over her husband who died while on active duty. This man, however, is lauded by the show as the good guy. He isn't the only problem of course. The other characters are either completely inconsistent or overblown caricatures. Oliver Platt's character is the only shining light among them all. A miss for me unless I need to watch because of a crossover with the other, superior Chicago shows.
I really love this entry in the crowded ghost story re-enactment genre. This one is similar to Paranormal Witness, except that the stories are completely made up, but based in part on people's reported experiences. For some reason, they chose to hire actors not only for the re-enactments, but for the story telling/witness segment as well. You'll notice the people telling their stories are really well spoken - there's a reason, they are actors. I'm not offended by the stories being fiction like some people seem to be. I can overlook this pretty odd choice, because the stories themselves are really good.
