No, mono has no true discrete directional effects, because it is a single channel for all the audio. Done well, of course, you don't need to have directional effects to immerse you in the audio; if it is played at sufficient volume with sufficiently good equipment, you won't be paying attention to it because the quality of the mix itself is good. This is much like if you've ever been to a rock concert, where there is a 50/50 chance the mixer is sending one mixed channel to all two dozen speakers in the venue. In the case of Star Wars, unfortunately, the mono mix is a handmade slapped-together version made out of various sources, none of which were designed for home theatre viewing, and so it is understandable to find this less than enthralling. It was reconstructed as a historical curiosity more than anything. But, since all viewable versions of Star Wars are of equally subpar quality, I find it to be surprisingly consistent when paired with the image.
