Yes there are cut scenes but they help to sell the story and you can skip them. Again there are fetch quests, kill quests, etc. but then a game like this is always going to be that and if you can show me any examples of any game whereby, fundamentally, the game isn't like this I'd love to know.
The story is what hooks in people, hence why there is a TV series. Underneath it all though there is a very good game. The graphics are superb, the game is very modable, there is a new HD update coming in Q1, etc. and it's very open World. It doesn't demand you follow the line - you can veer off to anywhere. The DLC as well adds hundreds of hours but like any game it's not for everyone.
Also if you can't beat a boss then you need to check if you're the right level for it, if you have potions/food, learning how to dodge, etc. but there's nothing I really got stuck on for a long time.
