Personally, I don't hate VATS, but I don't understand at all why Bethesda thought it would be a good idea to include it at all. And I'm not even a Fallout fan crying over changes. I thought I was alone, but it seems most people think it looks distinguished mentally-challenged.
It's good that it's optional, but my main concern is that some enemies or parts of the game might be extremely difficult unless you resort to VATS. A bit like those enemies with the hard armour and tiny eye where they're vulnerable.
Don't get me wrong, I'm getting the game and I'm sure I'll enjoy it as much as Oblivion in spite of being ugly, clumsy and clunky (like Oblivion).
