Yes, buy it, and ignore the people who hate it. Here's the deal, you'll love Skyrim from hours 1 -> 50. You can still probably love it from hours 50 -> 70. Around hours 60->80, you realize, "eh, the game can be formulaic..." and then at hour 80->90 you're like "well this isn't really that great anymore, but I've done so much I may as well complete these X questions." After hour 100, it's "I'm playing it because I've been playing it so long."
But, the fact that it takes 100 hours to hit that is impressive IMO, and I think the game is really great, and you'll even discover new things you didn't know before at every new hour milestone. Buy it, give up your life to it, enjoy it, and then 100 hours in, complain about it on gaf.
