No, it's not a remake.
Why not just see it now? If you're willing to fly Economy (shudder), you can get the 18:20 from JFK on Virgin, arrive nice and early Saturday morning, watch the film a couple of times, then hop on the 14:00 Sunday back to JFK, all for under $1000
They awoke Khan because Section 31 wanted someone to develop weapons? This was a WTF moment for me. Did I hear that right? Also 300 years old means he was exiled in 1959? Should've said 200 years.
"300 years" is about right. 250 years is more of a mouthful. 200 years is nowhere near when Khan was exiled.
