This thread is pretty much over with Matrix Revolutions. But we'll keep going.
Texas Chainsaw Massacres - first was awesome, rest sucked
Kill Bill - second one put me to sleep
Oceans Twelve - second just didn't have the heart and soul as the first
Resident Evil - I actually liked the first one, but the second was awful
Indiana Jones - I HATED the second one, it was so dumb and was pointless. "Sure I'll help you random tribe get your stone back, I have nothing better to do." Thank god for The Last Crusade
Bad Boys 2 - wait a minute, Bad Boys 1 sucked too, sorry
