You feel bad for not liking some critically acclaimed games? Talk about first world problems.
I've laboured through games to see what the fuss is about ... sometimes I find it, sometimes I don't. I'm glad I stuck with The Last of Us (really glad) but Saints Row The Third was basically a game of tutorials IMHO. But I don't feel bad for having an opinion different to other people's. Life's too short to play games other people like and I don't.
Moon was great... but I didn't really care all that much for the guy and when the big reveal happened about him being a clone all I thought was "yeah, that's how these movies go". I really liked it, but it had it's flaws.
Gravity made me feel sick sometimes with dread. The constant threat of death was relentless and the lengths she goes to survive kept me engaged. I cared more about Ryan from Gravity than the guy from Moon whose name I can't remember.
I still think Moon is brilliant, but I just think Gravity is better all round.
And Niel deGrasse Tyson can piss off if he thinks the only reason to watch a sci-fi movie is for the science. He comes across so pretentious sometimes.
