Alas, film critic Gene Siskel (of the Chicago Tribune) is no longer with us to parry with Roger Ebert (of the Chicago Sun Times) over the release of Indiana Jones and the Kingdom of the Crystal Skull. But for those of you who used to eagerly await each new episode of Siskel & Ebert, here's a blast from the past, as the two titans of movie reviews give their take on the previous installment, Indiana Jones and the Last Crusade. While Siskel gives the film a thumbs down, Ebert's endorsement sheds light on  his positive review for the latest Indy flick.
