Hmm... looks like it might have been interesting! Was on when I was living in the UK without a tv, hence my ignorance...
Don't feel bad. The network that bought it seemed to be bending over backwards to screw it up: episodes run out of sequence; weird time slots; irregular intervals between episodes, etc. It was almost as if they wanted it to fail. You can read all about it up on the fan sites.
Since it's gone - and won't be coming back - you could also start with the feature movie Serenity. WARNING: There are three major spoilers in the film (two of which are what used to be called "absolute bummers"), so if you want the full "Firefly experience" you'll have to watch the episodes first. (I didn't) The episode entitled Our Mrs. Reynolds is an absolute gem. It contains some priceless dialog that sets much of the tone for all the later episodes.
There are probably a lot better uses for $50 than to buy the DVD set of Firefly. However, I can't think of very many.
