oh man, you need to at least see up to 6! 6 is very good, and 7-10 are entertaining also even if they don't feature all the great side characters from 2-6. overall it's a great series and i really hope it gets renewed, there's so much material to play with.

as far as exploration, yes def!! she'll welcome anyone who wants to help her attempt to figure out what's going on in this place, and especially if they're wilderness-savvy. johanna isn't exactly an outdoorsy girl, so she'll probably need help in that arena!
