Hi, English language professor here.
There’s nothing wrong with saying something is tremendous, when in fact it’s just rather good.
This is an example of human beings using language to exaggerate for effect. It’s not new.
To binge something literally means to do something to excess, often in a way that many would consider to be too much.
So, binging television. Works fine. It’s not any kind of attempt to be arty or clever*. It’s only a language phenomenon in the sense that all language mutates and develops over time. Been happening for millennia.
*Though some might say armchair kvetching with authority, when you have no solid basis to talk about the subject at hand might be an attempt to be arty and clever.
