I don't think it's quite as engaging as Bigger, Stronger, Faster*, but it's an interesting (and heartbreaking) follow-up on the Bell family. I think the biggest difference is that BSF had the benefit of lots of wrestling and bodybuilding stuff to use as footage, but there isn't a whole lot of material to use as visuals in a documentary about meds, so they throw in a bunch of movie clips for gags. It works all right, but it's not the same.
