To me, they're in an odd balance between Lynch's version, and the Villeneuve version. The visuals were much better, but because it was broadcast, were mostly experienced on TV's that couldn't do them justice -- but at the same time, they also weren't good enough for cinema anymore. And in a similar vein, unlike the Lynch version, they followed the books much more closely, which to me made them lose some of that warm fuzziness charm. I also can't say that the acting was particularly memorable to me, which is to say that nothing stood out as so bad as to be memorable, but I can also barely remember who was in it.

And as far as the sequel, Children of Dune goes, that year BSG blew it out of the water for me.
