Inga is the weakest Joe Sarno film that i have seen. It's quite boring without any plot! It does not progress and it never climaxes. On the back cover, it says that this is an erotic masterpiece, which is far from the truth. I think that Joe Sarno tried to make an art film but the result was disappointing for me! I expected a lot with INGA. A film that was a huge hit. Earlier films by Sarno like "Sin in the suburbs" and "The love merchant"are much better. They are more dramatic with good stories. The transfer by retro seduction is very good, just watch the dubbed version and not the "original" swedish. I have not seen the other two films, yet.
