Not at all. It's just the internet to hate. I wouldn't be surprised if a lot of the people criticising it haven't even played it. Most of the Youtube videos are people just looking for hits. Their channels are generally full of the same negativity, also based on not playing the game. We also like to leave a thread on a negative as whether we have played it or not, if we are hating on it, the thread has to end on a negative. It's why you see the same repeat posts after someone posts a positive in any game thread.
The game has issues don't get me wrong. I can understand someone saying the way the story and quests unfold is not my thing, the multiplayer is off-putting or I've had performance issues. But none of these make it a bad game and the latter is generally improved as we go along (although I've had no performance issues, one crash so far and a couple of mobs stuck in walls). There are bugs but which game of this nature and scope doesn't have them?
I've found it very immersive, the world is interesting to explore and if you get a kick out of just being in a huge Fallout world with loads of interesting things to discover, this might be for you. Just don't expect amazing combat (although it is fun and a good laugh in a team) or to be the hero who makes everyone feel better about themselves. I've also played a fair bit of multi with my 2 sons and we have had a whale of a time. I'm not sure if this will change but it's quite easy killing 1 or 2 mobs much higher than you which makes exploring a lot of the map pretty easy.
Biggest gripes so far are silly things like not getting XP for a kill in a group if you don't damage the mob although this could be a bug. Stash space but there are ways around that. We went to a new town yesterday and a couple of quests were bugged but no biggie, we'll come back when it's fixed. So far they are the only issues I've had, maybe I've been lucky.
