I haven't read Billionaire Island but so far I think this is the closest Russell has gotten to his Flintstones run, it's just a damn shame it's still not that good. So far I'd say Wonder Twins was better but Wonder Twins had its own cringy moments as well.
Maybe because most of these characters are relevant still so any attempts to recontextualize just falls flat for me.
Some of the monologues still do work but a lot of them feels more bitter and cynical.
