Fighting Demons was met with generally positive reviews. At
Metacritic, which assigns a
normalized rating out of 100 to reviews from professional publications, the album received an
average score of 73, based on seven reviews. Writing for
NME, Kyann-Sian Williams gave the project a rating of 4/5 stars citing that
Fighting Demons "shows the other side of Juice Wrld, which was never explored enough while he was alive" and that the project manages to deepen his narrative with a level of care rarely seen on posthumous releases. Reviewing the album for
HipHopDX, Mackenzie Cummings-Grady stated, "
Fighting Demons embodies Juice Wrld in that way: a flawed project with moments of brilliance that feels uncomfortable to listen to but isn't ashamed of its naked humanity. And in that aspect, it becomes a balancing act of the man and the artist, melding the two to create a project that's earnest and authentic – just like Juice Wrld". Fred Thomas of
AllMusic said, "Themes of struggling to overcome depression and drug dependency surface often on
Fighting Demons, making it a heavier collection than the sometimes celebratory memoriam of
Legends Never Die. It's not an essential piece of the Juice Wrld story, but it's also not without some solid reminders of his greatness".
Rolling Stone critic Will Dukes said, "
Fighting Demons, his second posthumous album is a tortured but overall grateful memento mori from a talented artist who left us all too soon". In a lukewarm review,
Clashs Robin Murray wrote, "Ultimately
Fighting Demons works almost as a tribute record, gathering fragments of his undoubted genius. Whether it's a true Juice Wrld album, though, is another matter". ==Commercial performance==
