I used this ability last year OCCASIONALLY. it is doing things this year that I don't remember it doing last year and I feel like it's actually really strong. A lot of people run 4 plays on offense and come out in the same one every play and then audible. Well film study now shows what hot routes they're making as they make them which is hilarious when you just start moving DBs to where the route is taking the receiver. The second thing is that you can actually see what play they switch to if you're holding your trigger when they switch, even if they haven't ran it enough to hit the film study threshold. If you're holding your trigger while film study is active it will very briefly show the play art of the audible. (Hopefully not a glitch lol)
Wanted to put this out here to raise awareness and help combat the cheese.
