A "Lake of fire" is fairly descriptive while the Bible tells us that eye has not seen nor ear heard" concerning what awaits those of us that trust in Jesus. There are many descriptive phrases concerning heaven: gates carved out of a single pearl, gem colored adornments, river flowing from the throne. Hollywood has been prolific in depicting evil, but I don't believe we can envision even the entirety of the horrors awaiting those that don't put their faith in Jesus.
