Viewers complained about intense religious imagery and a late shift into psychological horror, which built up to an ending that many saw as abrupt and opaque. TV stations received a wave of complaints, and the production team reported harassing messages that escalated as the finale aired.

The backlash prompted the creators to produce a feature-length reimagining to address the controversy. Retailers and magazines documented a spike in letters and editorials about the series, and broadcasters added advisory slates when scheduling reruns.

An early episode featuring rapid flashing effects led to mass reports of photosensitive seizures during its original broadcast. The incident triggered medical reviews and forced the franchise to overhaul visual guidelines for future episodes.

The show also faced separate criticism over a character design that resembled racially insensitive imagery. International distributors altered scenes and paused circulation of affected episodes while producers revised the character model for later releases.
