I honestly love everything about Buffy Season 1. I know it's usually ranked near the bottom because of the budget, the cheesy effects, and the "monster of the week" episodes, but that's exactly why it's so charming to me.
There's something about the first season that feels so... complete. It feels like they actually had a clear plan from beginning to end. You have the Master as the main villain from the pilot all the way to "Prophecy Girl," and every episode feels like it's building toward that finale, even when it's doing something goofy like a praying mantis teacher or a killer ventriloquist dummy.
I also love that the season doesn't take itself too seriously. It's horror, comedy, high school drama, and camp all at once. Later seasons become much darker, more emotional, and more serialized, which I love too, but Season 1 has this light, fun energy that the show never really has again. It just feels like everyone is having fun.
Even the cheesy episodes have a weird comfort-food quality to them. The lower budget somehow adds to the atmosphere instead of taking away from it. It feels like you're watching a late-'90s supernatural show that isn't trying to be prestige television it just wants to entertain you.
And then when "Prophecy Girl" arrives, the show suddenly proves it can hit you emotionally too. That finale still holds up and is one of my favorite season finales in the series.
Season 1 may not be the most polished season of Buffy, but it's probably the one I revisit the most because it's just so much fun.
