All the few shows/movies on my hard drive I end up watching when I get around to it and feel like watching. Though, recently, there have been 3 specific cartoons I've been watching a lot more of due to not feeling like watching other shows.
So far, the only things I have got that were bad quality and unwatchable were 2 cartoons. One you could easily tell it was upscaled and just looked a bit off, making it feel uncomfortable for me to watch and enjoy. The other, first episode in and they cut the theme song and had the channel watermark, for a show that's a few decades, so I didn't bother checking the other episodes and just deleted it. With the first show, I looked immediately because there was a specific episode I needed to check, but the other, it took me over a half a year to finally check to see how good quality it is/was.
