Can you watch 3D blu ray movies on a regular lcd tv?

That depends on the kind of 3D TV you have. If your 3D TV has a 2D to 3D conversion feature than yes, you can watch any 2D program in 3D. LG makes good 3D TVs that are affordable and have 2d to 3d conversion feature (other cheaper makers don't have that feature included). I have a LW6500 model (Cinema 3D line) from LG and 3D-converted images look great.
