Well I do look for rationality in my reviews as well, and I always avoid stupid user reviews. A good baseline is to avoid any score of 0. That's pretty much just trolling. I just mean that I really appreciate when critics are, well, critical, and try to hunt down reviews like that.
As far as Journey goes, it struck me more as visual art than anything deeper. If anything, it's an exercise in simplicity. Simple game mechanics, simple, but polished art style, even the music isn't all that elaborate, but it is beautiful. I think that's the message I walked away with, if you can call it a message. Journey was a lesson on appreciating beauty in simplicity.
