Just had a quick look through ESB Lee, and it once again looks fantastic. I haven't really watched it properly yet though, but for the most part seems excellent.
What surprises me is how similar the colours are to the 2004 SE in lots of parts where I thought it was actually different. Hoth is shocking more blue than I remembered, except for one or two parts. It's almost as if the 2004 is the exact same colour except with more saturation. The only thing that really stands out that is different (in terms of colour differences) is the lightsabers. Here in the 1997 SE the lightsabers are strong and vibrant whereas the 2004 SE they are much more muted. Quite interesting.
