That foreman wasn't knocking your work, he was telling you there's a level past code that most guys never bother to chase. The frustrating part is you can't learn it from a book or a video, you only get there by doing it over and over until your hands know. Three weeks of that is worth more than a year of someone just telling you it looks fine.

Watched my sister do the exact same thing with a book once, she tore it apart chapter by chapter for a class and I almost skipped it, then I read the whole thing in two days and loved it. It seems like knowing all the flaws ahead of time takes the pressure off, so you stop expecting some perfect masterpiece and just let the thing entertain you. Critics and teachers are trained to spot what's wrong, but that's not really why most of us watch movies in the first place. There's a real gap between a movie being well made and a movie being worth your time, and plenty of smart people can't see that gap. Sometimes the dumb stuff is the whole point, and the person pointing out every mistake is just missing the fun on purpose.
