Super Freak
Your right.. I should not have heaped on... But when fighting Superman you might want to plan for getting slammed into the ground or through a wall or something. Best to have some protection... It was also obvious IMO that it gave him more strength.
I think you overthought it just a bit.
Maybe, but I also think that a lot of people who liked the film were quite happy to gloss over details like this. Not that that's an issue, whatever floats your boat. The added strength isn't necessarily obvious, seeing as Superman was weakened, possibly to human level strength.
