Two episodes in I like it.
Good to hear, welcome aboard. It's a great show.
Am way more interested in the overall plot than the weekly plot lines.
Then definitely keep watching, because the "overall storyline" kicks into full gear soon for you and keeps going after that.
Once you get into the series there are fewer "moster of the week" episodes...those kinda change to "independent" episodes, whereas there are less mosters to figure out, but they have their own plots. However, they do a good job of tying those shows into the overall plot pretty well.
Also, it can get confusing at times, so it's good that you're sort of shotgun watching the series...that should help you stay on top of what all is going on. Also, the major plotlines change a bit several times, so if you ever feel like you're not digging one, stick with it and it will eventually lead to something a little different.
All in all, it's a great ride and a really fun show. So like I said, welcome aboard. Keep bumping this thread and let us know how you're progressing and what you think. If you're digging it two episodes in, you'll really enjoy the series.
