It's always like this for a few days after a big release, the people who love the game are too busy playing to bother posting.
My advice is just to ignore the negativity.

So far, the funniest surprise was a cheeky comment from an NPC about rummaging in rubbish when I was checking out some barrels outside a house.

I was also very pleased and surprised with the detail and fun of the first side quest I picked up. The game is superb.
