Loved it, definitely worth a watch. I didn't have any problems with the video quality, looked good on the TV. 90% of the movie is in the Haberdashery Inn or the snow/forest so I don't think the video quality is really super important anyways. The 3 hours definitely flew by, but I'm glad I watched it at home since I took a few small breaks and it was nice drinking some spiked eggnog to go along with the winter theme.
I'd definitely put this somewhere in 3-5 in my ranked Tarantino list, the actors were all just perfect as was the script and I loved the setting / themes of the movie. The only real thing annoying to me was Tarantino doing some of the chapter narrations, his voice is nasally and immersion breaking.
