I agree totally.
3D films have been around for such a long time now and it seems that they appear in groups at well spaced intervals to give us time to breed a new generation of moviegoers or to give us time to forget just what a waste of time they are.
Jaws 3D, Freddy's Dead, Final Destination 4 and My Bloody Valentine are all in my collection as 2D versions. If I want 3D action I'll play sports instead.
