For similar reasons, all streaming sources (NF, Amazon, Vudu, etc) are utterly valueless to any HT-phile and/or film buff.
Valueless to the HT-phile because the codecs, bitrates, filtering, image cropping, ad content, bugs, snipes, etc are never known and/or can change from one day to the next. All streams will eventually add forced ads/bugs/snipes if they don't already. Also the inability to keep/record a stream you've paid for if you choose (at least easily).
Valueless to the film buff because titles can be removed from availability on a whim, edited/censored moving forward due to political correctness or editing for any reason, change the aspect ratio, etc.
The printed disc (DVD and/or BD, even LaserDisk) will *always* be the benchmark and Master of any film release (fan subbed/dubbed/edited darknet editions notwithstanding) for HT-philes and film buffs.
