Pixels 3D currently at Best Buy for $16.99.
My personal opinion is that it's worth it, but I seem to be in the minority of those that thought the movie was a pretty fun ride.
Regardless of opinions on the film itself, the AV presentation is stunning (despite the Atmos track only being on the 2D disk, which is why I'll be remuxing my copy to remedy this).
The 3D is above average in this. The intelligence is below average. The humor is, well, for Adam Sandler, about average I'd say. So not a bad deal for $16.99 imho.
