Yeah, I forgot to mention that. Also, there are two entrances into Blighttown, which one did you enter through? It doesn't matter in the longrun except one way is a serious shortcut, literally straight to the boss, if that's what you want. I personally explored a little (and activated the bonfire, obviously). There's also a Fire Keeper Soul somewhere in Blighttown IIRC, which you're going to want to pick up.
The only problem I had with Blighttown personally was the low framerate and the poison/toxicity. The boss battle is a lot of fun though.
