Yeah, I loved it
Some of the effects, the bike chase especially, showed it's limited budget and looked a little bit more like a game cutscene than a film but the rest of it was so much fun I didnt give a toss
Loads of cool one liners. Felt like a cross between Escape from New York and Fortress. Seemed happy to just be a fun B movie, and like you said, the crazy scottish fucker tore it up whenever he was onscreen.
