I give it a 2.
Might be a little harsh, but the only fight that kept me going was the Munoz-Grove fight.
The Hughes-Gracie fight was how I thought it'd turn out...pretty boring. Im a big Hughes fan, but lets face it he is past his prime and DW had to give him someone who is even farther over the hump so that Hughes could finally win one standing up.
the Penn-Edgar fight had its moments, I liked the technical striking involved with the fight, but all in all that fight left me with alot to be desired as did the Anderson Silva fight.
Silva could have finished Maia at any point that he wanted to in the first couple rounds...so that really pissed me off as well.
All in all, this was probably the overall worst showing I have seen in quite some time.
