I'm a fan of fantasy in general. While this show isn't canon
Tolkien, I'm enjoying it as a standalone fantasy series that's influenced by Tolkien (as so many series are). It's definitely not perfect and has some poor writing but it's not awful. But as I've said so many times, it's not hard to just not watch if you don't like it. It's as simple as closing out of Amazon Prime and/or not watching in the first place.
It's not going to change what Tolkien wrote or did in his life. I know some people personally who never had read Tolkien before. Now that they've watched the series, they're interested and have been discussing the original
books and lore to understand better. A couple have even joined TTF and /r/TolkienFans on Reddit (another excellent site for Tolkien discussion). So I'd say that's a positive for the show too.
