I did. I've had a love-hate relationship with it over the years.
Season 1 was great in my opinion. It was always campy and not to be taken too seriously, but the characters were interesting, the acting was good and the story was very well executed.
Season 2 and 3 both had a few growing pains, but overall they're both pretty solid.
Season 4 is where the consistency gets pretty shaky. We get a lot of characters coming in and out, certain plot points are introduced and then forgotten about. The rules of the mythology get less and less clear. However I still think it's at least fun for the most part.
Season 5 is the lowest point for me. The continuity is bad, the characters often look stupid or heinous and the writing is all over the place. There's a lot of squandered potential.
Season 6 is still pretty messy, but the second half is a big improvement and they wrapped up the story as well as I could've hoped for at this stage.
