If you guys don't finish Journey, it comes as no surprise that you're not "getting" it.
If you finish the game and still don't like it, I can respect that opinion as boiling down to different tastes. Until then, your opinion is based on incomplete information. Journey is a short enough game that I don't think you'd hate yourself or me [too much] for seeing it through to the end.
I loved Journey, personally. I've only played through it twice, but I enjoyed both playthroughs. I also loved Brothers: A Tale of Two Sons and Gone Home. And I only recently finally completed The Last of Us, and I think it displaces Uncharted 2 for me as best game of the previous generation.
My tastes are all over the place, but I will generally like a game with well-executed mechanics and a great story. Story can trump mechanics, as I also enjoy some of the TellTale games. Journey does hit both of those criteria, for me.
