Personally, I prefer the "Supernatural" episodes that revolve on random malignant encounters rather than those dealing with the Winchester horrendous family history, but this is the season's finale and thus the end-fight with the demon that killed the boys' mother is long- anticipated and inevitable. The previous episode "Dead Man's Blood" illustrated how Dean and Sam convinced their father John to fight the demon together and how they recovered the only weapon in the world capable of destroying it. "Salvation" further builds up towards the confrontation, as father and sons discover where and where the demon will strike next. But the demon's sexy sidekick Meg is still in the picture as well and she continues to slaughter John's old friends in order to recover the Colt handgun. "Salvation" is a rather mundane and unmemorable entry in the brilliant first season of "Supernatural" and it too often feels as if it was only filmed to assure continuity and properly conclude the Winchester family background introduced in the pilot episode. This episode doesn't really contain any truly memorable parts or gimmicks and, given the serious toned subject matter, there aren't even blackly comical moments or any references towards classic horror. The best part about "Salvation" is the character of Meg, who gradually – in four episodes time – became a deadly sexy villain character who sadistically enjoys boycotting the boys' mission and killing off their entourage. She's definitely a lot cooler than the demon Sam and Dean have been searching for throughout 20 episodes. His/its appearance was a bit of a letdown thus far, I hope it'll be more worthwhile in the next and actually last episode of season 1.
