The trouble with indies, for me, is finding ones that I like. People praise the originality of indies, but so many of them seem very similar to me (all the 2-D platformers, for example). I find that I have to wade through piles and piles of games I don't want to find a few gems.
I have found them. Journey, Oxenfree, Firewatch, Inside, Gris -- these were good experiences, some of them great. But the amount of dross that I have to wade through, to find them. Indies generally get very little publicity, so it's hard to find the ones that really stand out. I consult "best of" lists, but even there, most of the games just aren't to my taste. There is the occasional find, but it often feels like looking for a needle in a haystack.
I started this gen very optimistic about indies, but as the generation wore on, I became disenchanted. There are some good ones out there, but they seem very few and far between, to me. YMMV, of course.
