That's another film on my "to watch list". Just not a priorit. I love the Power Armour i envisioned while reading the novel.
Hopefully a brief percentage should hold true......
Skip it. Seriously. If you want total Marauder-powered ownage, go watch STC, some of the Pluto sequences or Rico's rampage through a hive with one. (God what I would have given to see one of duck Marauders plasma-walling everyone, wipe the damn taint from my mind.)
I had high hopes, I rather liked the way the Marauders moved at first, more mechanical then human, and they seemed to be suitably impressively armed. But the pyrotechnics sucked, you barely saw them moving around at all, and they get maybe 3 minutes of screentime if that.
