Anything with Clint in is worth watching, even his never-ending machine gun blowing away half the German Army in Where Eagles Dare.
But yes the Spag Trilogy is well worth a wet Sunday sit in front of the TV with a Beer or Two...
Godfatther 1 and 2 were wonderful, Godfather 3 much less so
Terminator and Terminator 2 also wonderful, Terminator 3 very much less so
Alien and Aliens were great, Alien 3 was garbage.
Anyone see a theme beginning to emerge?
