I know there are some who are less than happy with certain episodes. I am not one of them. I have thoroughly enjoyed this series...Jared (Sam) & Jensen (Dean) are completely perfect for their roles ~ I almost can believe they would be brothers in real life. I especially enjoy the humor between the two main characters...yet, when they are angry or disappointed with each other, I can completely believe it. The special effects are excellent, the acting (by everyone involved) is way above par. There is so much in this series ~ much more than one would expect from a TV show ~ I can't even begin to go there... Being my age (65) I can remember "way back when" the lack of quality to a TV series ~ canned laughter, etc. ~ this show is among the best as far as I'm concerned...it keeps me engrossed from beginning to end...so much so that I hate to turn it off when it's time to move on with my day! One of my favorite features is the ongoing variety of fantastical characters. So many I would have to watch from beginning to end once again, just to remember them all... Right now my only complaint is that, even though I have bought every season on my Amazon Prime watch list, I can't make up my mind if I want to go ahead & order the DVD set as well. Decisions, decisions.....
