Start at the beginning and go forward. Otherwise, you will have spoilers. Every season, they make mention of previous winners. I started at 9, and learned all about a particular player before I'd even seen the season he was in. So I started at 1 (don't bother, it wasn't worth it) but Season 2 was great. Season 3 is a personal favorite of mine. Like you've already heard, the more recent seasons are kinda blah.
