It really depends on what you're looking for...
If you're looking for Civ4 with frills, then you still won't like it.
If you accept it's a completely different game, more strategic, and with 1upt, and are prepared to have an open mind about it, then you'll probably like it.
Civ5 is not like Civ4, it's a completely different game, comparing them is not usually helpful.
1upt is not the problem, it works for chess and go, and it works for Civ5 as well. As far as most of us are concerned, it is taking the Civ series forward. There are still a few problems to be solved, as you would expect with so radical a change, but, imho, they are getting there...
