I've read that it's also possible, at least for some headsets and levels of correction, to purchase custom lenses such that you don't need glasses at all while wearing the headset.
Now I can use my Quest 2 without glasses :)
Not only watching videos but even reading text is much easier in the latest headsets. Unfortunately many people have only tried the older or commodity VR solutions and think that's the limit of the technology. This is largely due to the price and physical setup required for some of the better headsets, but already there are some great setups out there.
My headset had a sweet-spot where the image was clear on maybe 5% of the screen, making it potato-vr for video and text. Others (on reddit) had the same complaints.
If you're considering buying one, make sure you're also able to return it in case the lens-quality of the batch is sub-par.
I like the VHS comparison, but I would argue it's worse than that because you get a weird screen door effect if you're on any kind of angle that tends to distort things weirdly. I think Netflix had a decent tradeoff where the "screen" was rather large, but it feels like sitting in the front row of an IMAX where you're moving your head to see everything.
I use mine to watch 3D movies and it's pretty great. I missed out on seeing Avatar in theaters so being able to watching it in 3D without waiting for a re-release or anything is convenient.

This essentially means the quality is up to you. I usually re-encode 1080p+ files to 720p to add volume gain and burn-in subtitles. It looks great, imo.
