How do you not accept LC as an Indiana Jones film but
do accept KOTCS?
Don't get me wrong, I love both, and you're entitled to your own opinion, but if you thought LC was goofy, well, KOTCS just makes it all goofier.
LC was the 1st Indy film I seen, and till this day, I believe it has the best mix of action and comedy and is one of the most enjoyable "family" adventure films one could ask for, followed closely by KOTCS. But thinking LC is a parody of IJ? It just doesn't have as dangerous of a tone as RotLA does. If it was a parody, Indy would be clumsy and falling out of nuclear fridges, swinging with monkeys, and taking absolutely no damage from enemies.
Oh...wait.
