Good movie, but best of all time? Hardly . . .
Best movie ever!
A film with more than the usual spoiler issues. Talking about it in any detail feels akin to handing you a gift-wrapped present and saying, "I hope you like it -- It's a thriller about a diabolical secret experiment."
Let me be very fair here, this is not the best movie in my opinion. But, this movie is fun, it has purpose and is very enjoyable to watch.
