IIRC whisky said something about having seen it in 2D at the cinema, so I can see from that perspective it'd be a big letdown, after hearing everyone go on about how amazing it was. As a work of art, though, you have to see it in the context it was intended to fully enjoy it. You're not going to appreciate Guernica fully if it's printed on a postage stamp and you're not going to appreciate Avatar fully if it's displayed in 2D on your laptop screen. That doesn't mean it's bad art.
If you wait to see it on the small screen, then your suspicions will probably be "confirmed", because I'm sure you'll be underwhelmed by it in that format. When I see the adverts on tv it looks like a completely different movie to the one I watched in the cinema.
As for whether it should be "best picture" or not, well, no, probably not. It's revolutionary in terms of how it looks and how it was accomplished, but as lots of people have said, the story isn't particularly original.
