It’s a fine line. Isn’t Medium like an endless talent show where we get to submit a new entry everyday?
A lack of showing off can get boring. By the early eighties “show off” guitar solos had become unfashionable. Bon Jovi focus grouped Slippery When Wet (first time a rock band had done that, I believe). The verdict? Needs more guitar solos, which they duly added and had their biggest hits ever.
Still, you’re right. If the underlying structure isn’t clear and concise, showing off makes matters worse.
