Sam & Dean Winchester, the BEST brother duo. I love their relationship and the chemistry that these actors have on screen together really seals the deal on making the audience believe that the bond is real. I especially enjoyed the visuals they were good for the time that this series was airing. The whole spin on demons, angels, heaven, purgatory, and Lucifer was creative. I appreciate that it wasn't the typical angels are good and demons are bad narratives that are usually being taken. However I can admit that towards like season 13-14 things do get alittle redundant and repetitive, almost like they ran out of ideas.
