What on earth would be more targeted than compromising pagers that only Hezbollah military is using?

At some point the criticism really gets absurd. There probably was collateral damage, yes. This is what you have to account for if you start wars against another nation. Repeatedly.

Opposite of targeted are the missiles that hit northern Israel.

For these people, there will never be an attack good enough, targeted enough, or proper enough

It's because they're not motivated by fairness but a pre existing idea of who is good or bad

In terms of collateral damage it seems much better than even the most precise missiles, though.
