I think Starship Troopers was quite low down on my list but sneaked in because it has some very entertaining parts. Being by Verhoven (like Robocop) it is quite dark and violent and has some subversive moments that make it interesting, it also has Michael Ironside who i've always liked since 'V'.
On the minus side it has some questionable acting at times. But is definitely worth a watch.
