Anyone else remember when movies were fun?

I guess that makes me sound old....

What i mean is, most movies are written to have some deep, purposeful "Message" behind them. Even today's Avenger stuff kinda go all friendy dramatic: love your coworkers etc... I suppose TRANSFORMERS skip the message serving part....

Anyway, I think back to Raiders of the lost Ark, maybe even Star Wars, where they did stuff that lead to other stuff, the ride was fun getting there, they kicked butt in the end, and it was over. Almost NO messaged pushed on you, just a fun, entertaining ride.

Have movie scripts gotten too serious for themselves to have fun in it?
Maybe I'm over thinking this?
