i liked danny in the film cos his character was the 'nerd' of the team, but in the series he's gotten less nerdy...but as for the actors, i prefer michael shanks cos he's just so much better...
and as for jack, i didnt think kurt russell played a very good jack, but he played the emotional bits very well, in the series Jack has lost the 'emotion' side of him about charlie and has become more fun...so i'd say rick and kurt are about the same for jack, but RDA has the edge over kurt cos of the comical side...
