This is how you correctly pull the heart strings and connect it to serious problems in the past and the hope for the future. The problem is that inserting a comic-based or super-hero based storyline usually looks ridiculous in a "serious" show. However, because Straczinsky knows where he's coming from, he successfully weaved believability (dirty, make-shift costume, "real" problems) into the world of the comic book ("Iron Cave") and amazingly added a touch of genious with the laptop database idea. The show never goes overboard, never drops into farsical state - it's just a hard, dirty look into the mind and the escape from reality, adding a great touch of hope at the end. Excellent episode!
