4 stars: best in category, or tied for best in category (arbitrary categories created in my mind)
3 stars: very good and I'd be happy smoking this, or at the very least I can see the merits and understand why someone else may love it
2 stars: I'd smoke it, but it's not great, or it's forgettable; I don't understand why anyone would prefer this, but it's not horrible
1 star: If I had the option to smoke this, or smoke nothing, I'd always smoke nothing
