For some reason i thought it was going to be a courtroom drama.
Jack Lemmon's performance is clearly brilliant. Baldwin's cameo amongst the best i've seen, and some of Pacino's lines are piss-your-pants funny.
The first half of the film is especially superb - the tension in and around the office building up as it pisses it down outside - splendid.
Honestly one of the most enjoyable films i've ever seen.
It also dawned on me how many fucking great films Kevin Spacey's been in. Madness.
