The best of the sequels. Inventively cast, particularly Eric Braeden as Dr Hasslein (although it's a shame they ejected his dispassionate scientific perspective for a more straightforward gun-crazy murderer by the time we reach the final reel) and interesting to have such a levelheaded President.
Because it's more than 20 years since I last saw this, I hadn't realised that his excellent "Infinite regression" speech is sampled on Quantic's first album. The fun to be had with '70s mores likely influenced Zemeckis and Gale's Back to the Future script, and makes for a surprisingly light-hearted section (particularly following Beneath's downer ending) .
I hadn't remembered how much of a philosophical approach to the fixed future is taken here and in the following films. Probably because I hadn't particularly absorbed the last two installments, I'd remembered the films as just setting out a cyclic paradox, when it's as likely that they actually present an entirely different future to the one that results in the destruction of Earth (albeit with common touchstones).
