Second this also. The biggest pitfall of Dramatica is to use it as another means of procrastination (we've all been there).
In addition, something instructive for me has been looking at the structural similarities of stories in a certain genre. This is both a logical and intuitive process. You have to get a feel for the personality of a story. Some patterns and parts of the model will be easier to grasp than others. Personally, I love thrillers, especially psychological thrillers. So I see OS Psychology/Conceptualizing everywhere now. Physics/Learning stories are a little harder for me to identify.
Once you get a feeling for genre patterns, then you can look at outliers -- films that appear to be in the same genre, but have a different structural arrangement. For example, if you like superhero movies, try to get a feeling for what makes the "personalities" of The Incredibles and Into the Spider-Verse different from your typical Marvel action movie.
If you liked A Few Good Men, it would be interesting to compare it to other courtroom dramas (though I'm not sure how many have been analyzed). Twelve Angry Men is one that I believe also has an OS in Mind, which intuitively makes sense.
