I actually liked The Core, for all its faults. It's not a film I'd bother buying for myself, but it will definitely get a rewatch at some point.

Interestingly, The Core is a great example of what can happen to a film if you don't constantly fight tooth and nail. I remember an interview with the writer who fought to keep the film at some level of scientific accuracy/possibility. This included fighting the studio on some of the more ridiculous ideas they tried to force on it, including a 'windscreen' so they could see where they were going, and believe it or not, dinosaurs at the Earth's core!

I'd love to see the guy's early drafts, just to see what battles he chose to lose so he could safely stick to his guns with the big stuff.

On an interesting side note, I rather like your t-shirt idea, while finding sjl's joking response rather offensive - but I couldn't tell you why...
