Agreed.
It really is all to do with viewing distance. Most people view from too far away because of the nature of room sizes and configurations. In that case the bigger the better. It's important to remember that 3D works because you're getting perspective displayed on the screen. If you can see the surrounding room and items in it that might lessen the impact of the depth showing on the screen. Basically for 3D you want to fill your field of vision or as close as possible. This principle applies to 2D viewing as well, though it's not dependent on it in the same way as 3D is.
Recommended viewing distances vary based on where you look and who's saying it but general recommendations from organisations and companies such as THX and other calibration specialists state a 1.3:1 ratio is ideal from what I recall. Some state closer, others a little further away. I did some investigation before building my home theatre and settled on a 1.1:1 ratio (100" or 254cm screen viewed at 280cm) and I can tell you that for me it is perfect. The screen fills your vision without the edges bleeding too far into peripheral vision. In my opinion anything more than that ratio will only result in the viewer losing focus on important info on the screen. Anything further away and you'll start to see things in the room start to enter significant portions of your peripheral vision.
So, if you're seriously considering going 3D I would recommend that you purchase a screen that is around a 1.3:1 ratio or so meaning that if you bought a 55" (140cm) screen you'd be sitting around 180cm away. You'll likely find this is a LOT closer than where you are sitting as if it's a living room setup most people are 2-3m away from their screens. If that is the case, all I can say is go as big as you can afford.
As for 3D, I enjoy it though it's not a "must have" for me which I know sounds funny considering I own a 3D projector. I'm very picky when it comes to 3D. I won't just buy the 3D version for the hell of it - conversions are often an issue and I find aspect ratios to be an issue too. Although 3D works for 2.39:1 aspect ratio films I find that the effect works best on films lensed at 1.85:1. Again, it's all about filling the field of vision and 2.39:1 films don't fill your field of vision as naturally due to the shape of them.
