I thought it was pretty good too, but I still prefer the original TRON (though I haven’t seen it in ages…).
I prefer the original too. It holds a special place in my heart, really. As a little kid my brother and I rented it from Movie Gallery all the time (back when Movie Gallery was a thing). When a sequel was announced I was almost as excited as I was for TFA more recently. Both of which I think are worthy successors to their respective originals.
