So I gave in and bought Supernatural on DVD (Seasons 1-3), but oh the dilemma, i've only watched the first 4 and a half episodes, and i'm guessing there's some things that happen during the rest that are going to have me confused if i start watched season 4 tonight.

So, should I watch it and try and muddle through?  Or should I wait and just watch it some other time??
