This was a more or less disappointing at least for me personally it was entry in the otherwise terrific series "Supernatural", and I can think of a number of reasons for that. First of all, "Shadow" follows the downright staggering episode "The Benders", which featured villains of flesh & blood for a change. I know the series is called "Supernatural" and thus the next episode would inevitable revolve on malicious supernatural entities again, but crazed humans are just a lot scarier. Another reason is that this particular contains almost no link or obvious references towards older classics of the horror genre. Pretty much each and every single "Supernatural" episode so far was like a little homage to other films, with familiar types of monsters or obvious quotations. The type of evil in "Shadow" is some sort of prehistoric demon called the Daeva that gets summoned by a master and can only be seen in brief flashes on the wall. The image of such a demon is promising, but there's very little violence and bloodshed to enjoy on screen. Finally, the plot of this episode is once again related to the tragic Winchester family history and hence very mysterious. Whilst investigating some bizarre murders in Chicago, Sam & Dean bump into Meg; the girl with whom Dean almost hitch-hiked toward California but later in the episode turned out to be a dangerous seductress. For reasons still unknown, Meg's mission is to put an abrupt end to the evil-battling activities of the entire Winchester family, including the father. She even appears to be connected to the über-demon that killed their mother. As said, "Shadow" isn't the most exciting installment of season one, but it nevertheless remains a fast-paced and enjoyable method to kill 45 minutes of your evening. Dean's womanizing and witty one-liners are exceptionally funny, especially when he's making insinuations about the supposed romantic tension between Sam and Meg.
