Die Flucht ins Ungewisse

Why this has an average rating of only 7.3 is beyond me. This is really darn good, maybe not a "masterpiece" as some of the other reviews have stated, but one of those criminally underrated and overlooked movies. And, heck, starring River Phoenix for crying out loud. Why had I never heard of it? Yeah, it's got a touch of cheesy '80s things about it (music, clothing, etc.) but I've learned to overlook that sort of thing if it's actually a good story. Take this and another coming-of-age movie, _This Boy's Life_ (starring Robert De Niro and Leonardo DiCaprio -- why hadn't I ever heard of that one either?), and you have a couple of the best great-but-underrated movies in recent memory. I'd love a good explanation for why this should only get a 7.3 out of 10, given the quality of a bunch of material with a higher average rating. (I thought 6.9 was the average rating here. This isn't even close to just average.) Compared to the body of Sidney Lumet's work, this has got to rank right up near the top, doesn't it?
