The night of the last episode , Fox through a curve ball to all of us fans , and announced ,as the show started, that this was the ' series finale "!!!! This really aggravated all true fans.
They apparently shot two endings, the one we saw was where Peter was seen laying in a pool , of blood.
I rated this episode a 6 , only because of the way the network screwed us. They could have given the series a chance to wind it up in 2000, the so called beginning of the millennium we are now., which was actually 2001.
