The mini was shot with a tiny budget in Prague IIRC, so other than the main cast the rest are local Czech actors. While the girl who played Chani was good (better than Sean Young actually), others like the ones who played Mentats Thufir and Pitr were not. I think things like the Harkonnen and Sarduakar uniforms were appropriated elsewhere (from historical dramas?) and used.
They did things more like it was a play, actually, so if you don't like seeing outdoor scenes that look like they're indoors, you'll be ticked at that.
Second miniseries was quite good, although the ages of the various characters was really messed with.
