Although the magazine's handed out to the public are smaller and simpler nowadays, I think the argument that the content has become less intellectually challenging is laughable.
The older Awake and Watchtower articles may appear to have more stimulating content but the truth is that most of it is disable goble-de-hook such as
Giants v. Dwarves
Demons
All sorts of pseudo-medical clap-trap such as aluminium pots being dangerous and the heart really governing emotion, anti-vax rubbish etc
Even the so-called deep Bible studies are replacement theory rubbish such as the Franz's anti-type cobblers and the UN stuff.
Try reading it sometime. Its rubbish and always has been.
