Care to give any examples of why the Norse and Slavic deities turn out to be kind of stupid?
I certainly don't think they are stupid, quite the contrary actually - they are unbelievably
osom.
But sometimes it's unclear which god is responsible for what.
For example, Veles is known throughout all the Slavic world as
skotiy bog - the lord of cattle. There still are songs in rural areas invoking him to bring good health to cattle and make them breed. But in old Russian ballads like
The Tale of Igor's Campaign or
Beyond the Don Veles is mentioned as a grand father and a patron of musicains. In primal Slavic cosmologic myth of World Tree, Veles is the part of a duo with Perun the Thunderer. In this myth Veles is depicted as a
zmei (a dragon) and a ruler of Underworld. There's also an established etymologic connection between his name and an old Slavic word
volhv, meaning a magican, a sorcerer, a healer, a fortune teller and all that. Hence the name of the river on which Velikiy Novgorod is located -
Volhov. So Veles is also the supposed lord of magic and supernatural powers.
Another instance is the solar gods. There're actually 5 of them in Slavic pantheon:
Dazhbog, Yarilo, Kupala, Koleda and Hors. The first being the Sun in general. In some early church writings he is likened to Appolo. In Russian epic poetry the Slavs are being called
Dazhbog grandsons. The latter 4 are supposedly Spring, Summer, Autumn and Winter sun respectively, though it's not clear. There's also very archaic god
Svarog, having its roots in Indo-European pantheon, who is also the god of Heaven and Sun. And then again there's also
Sviatovid...
And actually it's unclear who is the boss in this Pantheon. The late paganism seemed to favour Perun the Thunder for that role. Earlier myths seemed to prefer the forefather
Rod and
Lada, the love goddess. And earlier - Mother Earth (
Mati Syra Zemlia) or
Rojanitse who gave birth to all and weave the strings of fate for humans, quite like the Norns or Moiras of Greek mythology.
So this uncertainity may seem uncool to somebody. Other than that - I dunno.
