I haven’t done formal research on the topic, but as far as I can see this is correct- alcohol just lowers your inhibitions and makes you more suggestable, therefore easier to influence by your enviroment- you’re way more likely to be depressed and sipping whiskey slowly by yourself than partying with Coronas with lime.
It would be interesting to look at regional ideas of what different alcohols are appropriate for and see if the “effects” change with it
I think that’s the real problem, they often shove tragic, supposedly heavy backstories on us with no time devoted to actually developing it and giving them weight- we are TOLD to care, instead of given actual reason to. If the movie can’t invest in their backstory, why should I?
