Steins;Gate is a masterpiece. Anyone who says otherwise without giving you definitive proof of some kind of bad plot hole or character stretch is simply a hater. Don't try to reconcile with them, cause they don't deserve to enjoy what this anime has to offer.
I really can't describe the experience of watching Steins;Gate, you've just gotta do it. If you don't do it, you're missing out.
It's great. Time-travelling and shit, confusing things and shit, Moeka's sexy body and shit. What's not to like?
