There are many, if you dig around. One of the problems is that websites that review indie games can be very much like indie games themselves in that they're usually small, specialist, hard to find and- because they exist 'for the love', they often come and go very quickly.
Often the best place to go to is websites specific to a genre or region. Our upcoming adventure game, for instance, has had coverage in Adventure Game Hotspot, przygodomania.pl and Quest Time (a Russian site). Also, there are individual reviewers such as FutureCopLGF who posts videos of the best Newgrounds games each month, there are microbloggers, forums, small collectives who enjoy playing indie games with friends, sites that enjoy indie games and do something different to promote them (like your own website! Thank you for covering Five Day Detective by the way ;) ), there are podcasts like Save Your Game with Pushing Up Roses, or the Adventure Games Podcast, there are thousands of individual Twitch streamers and Youtubers.
Essentially, there's a tonne of great indie stuff out there and the scene's alive and well, but it often takes some finding. I'd love for websites like itchio to do more to help give a platform for people who cover their games- maybe a specific forum? As this helps us all :)
