I am gonna give this time but what i personally did not like was spoilers:
Thor being a herald, that can work as a short mini-series but being the main driving force behind a new series is kinda sketchy to me, it basically makes everything Thor does void if he is gonna get the power cosmic now, Thor doesn't need it he is powerful enough on his own... i guess anything beats him jobbing so i guess i will give it time.
end of spoilers
