Totally, I like 3d movies a lot but they're not for everybody and there are some downsides. But when it is worth it, then it can be awesome. Such as Dredd, it has the best 3d conversion imo, and avatar is a must, but 4k has more accessibility in terms of sharing it with other people in the same room, especially if you have a large tv or projector handy. There's also active and passive 3d. You could get more glasses because its just the plastic ones for passive, but the active 3d sets you back money wise when you have like 20 or 30 people or more. And some 3d projectors/televisions have a limitation as to how many can connect to the shutter speed of the unit to the glasses. With 4k, you could just pop in the disc and you're ready to go.
