Sorry for the double post.
I've done some looking, and it appears Seasons 2 and 3 of Beast Wars (as well as Beast Machines) are still in print and readily available, but Season 1 appears to be tough to find. All the sites I've seen it on have it backordered except amazon.com, which says "Usually ships in 4-6 weeks." (In my experience, that means they really don't have it.) Used copies appear to be expensive and in high demand on eBay.
Why would this be? I've read that Season 1 isn't as good as the other two seasons, but is it really that bad?
It looks like it's available from the two rental sites, but that seems just weird that the first season is unavailable but later seasons are still in production.
