Another blockbuster action flick from Michael Bay, and probably his most excellent movie!  A disgruntled General and some Marines hold a bunch of tourists hostage on Alcatraz island (conveniently, the place is full of rusty but working jail cells!) and it's up to "chemical superfreak" Nicolas Cage and former "British Sheecret Shervish" agent Sean Connery to bust them loose and stop Ed Harris and his brigade from launching these deadly green balls of toxic chemical gas at the innocent citizens of San Francisco!  Those poor people have it bad enough having to go up and down 45-degree angle tilted streets every day, don't they?  We've got car chases, demolition, hand-to-hand combat, lots of things blowing up, and even some excellent performances (I was gonna say "acting", but you know...Cage is doing his over-the-top Cagey stuff...not sure if there's an Oscar category for Best Batshit Rant from a Lead Actor...).  Plain and simple, action and entertainment up the wazoo!  Welcome to The Rock!  You're in, mate!
