Any film based on an original idea that was tongue in cheek but is now presented in a dark and serious manner.
For example, Batman and all related superhero stuff are pure fantasy tales aimed mainly at kids. To "Upgrade" Batman into some sort of intellectual tale which is relevant to real life is just plainly ridiculous. FFS, a guy who dresses like a bat and goes round taking on the most improbable collection of villains clearly has a screw loose, as do the adults who lap it up and believe in it. The TV series from the sixties and the cinema spin offs were the only ones to have got it right, outrageously camp and with plenty of humour that would appeal to adults while still entertaining the kids.
And Superman - Clark Kent takes his glasses off, puts on a lycra skinsuit and even his closest friends don't recognise him.
James Bond is another - such an improbable secret agent is played for laughs and spectacular stunts and effects. Roger Moore got it right, the latter ones have lost the plot.
