Sounds good, it's not like the old show will suddenly not exist or anything.
Some aging fans probably dont get that the early seasons where computer/internet use is depicted as a mystic science only usable by the smart characters doesn't really work for an audience of young teenagers that won't even remember life before smartphones by the time it's released. Xander comes across as creepy in the 'Nice guy' internet era and Giles as less archaic and more just having skipped childhood for being a middle-aged British member of a global secret society in 2018 that can't even turn a computer on. There's no way that works in the modern era, but just as the late 90s had Buffy and co use the tech of the time to gain an advantage, that's something that can be updated to make it relevant to modern teens.
The most popular superhero stuff gets rebooted all the time. The characters that today's young MCU/X-men fans love are very different to the comics characters I loved in the 80s, and that's OK, I can reread the old stuff and also get the benefit of references added to the new stuff especially for aging nerds like me :D
