I watched it about three years ago. It is very dated by todays standards, however I preferred Tim Currys rendition of Pennywise, the lack of CGI and the general "feel" of the original. Some of that likely comes down to nostalgia though, because it was one of my favourite films as a child.
That's a fair point, I too have a soft spot for the mini-series due to nostalgia and scaring the living poop out of me as a kid.
