Here are my rankings after a long binge watch. I didn't watch them all in order, and I also had very minimal spoilers.

For reference I heavily enjoyed seasons with a lot of drama (i.e. BB15, BB11, BB19). I know these are some of the more unpopular seasons over here, but they were really fun to watch imo (minus the racism and stuff). I would say the core decision making in these ranking scores is entertainment value. That's probably what I judged a season on the most.

I've separated it by rankings, a score out of 10, as well as tiers. Feel free to roast my rankings or ask any questions
