My Direness Scale works on potential vs outcome.
A film has a huge budget, decent actors, good source material and is still a turkey is a much bigger crime than a low budget young director whith ideas that don’t quite pan out. And add a star for gratuitous inclusion of either space ships or Jim from Neighbours.
The high spot of awfulness by those criteria is Prometheus.
Indiana Jones the Crystal Skull redeemed itself with one scene.
But then it is self-selecting – I know not to put myself through anything with Jennifer Aniston, either of Brangelina or Tom Hanks. or anything based on a computer game.
