With the new Dune coming out, I wanted to watch the previous versions just to see how they all compare.  I watched the 20± year old Sci-Fi Channel Dune miniseries last night and realized that while I had seen it, I basically remembered none of it. 
Other than William Hurt, I don't think I recognized anyone.  They tried, but the acting was definitely on the B-side of things (some "overacting", acting like they were on stage instead of a movie/TV series, etc.), with some pretty bad fight choreography at times as well.  It told the story fine though.  Special effects were definitely not up to par for a 20-year old movie, either.
