Holy Sh*t I never saw this coming, as I thought The Bourne Ultimatum had the perfect ending to the series. But I will gladly see the 4th one as each movie in the series has gotten better the the previous one IMHO. And that rarely happens.
I'll hate to tell my brother about this as he's the one who told me that Matt Damon was threw with the Bourne series.
Heck it was my brother who got me to be a fan of the trilogy.
