I like this move even if it's a little outdated (practical effects are the best but Leopards as Panthers, bloodless firefights etc - typical 70s war movie) mainly because of wonderful actors. I also like how the movie made justice to Sosabowski (and he was in fact a scapegoat after Market-Garden), not so much to British XXX corps - if i knew nothing about MG I would assume battle was lost because Guards Amored were stopping every hour to drink tea
Big plus is that director dediced to show civilians fate during firefights around Arnhem as they are often forgotten in war movies when in fact they are main victims of any real conflict.
