The Real John Spartan

Is Halo a rip-off of Demolition Man?  In Demolition Man, the protagonist is a man named John Spartan, who gets cryogenically frozen and then is later thawed out when a threat arises that only he can pacify.  In Halo, a man named John, who is a Spartan, gets thawed out from his cryogenic sleep in order to stop an alien menace that only he can quell.  Both feature a female sidekick who annoys the protagonist at every turn, and has the ability to get inside the protagonist's head.  

I could go on, but why bother?  I've clearly made my point.

"But here's one difference...  When Master Chief speaks, people can actually understand what the hell he's saying."   lol
