Most of the shots in the beginning were pretty good I'd say. I feel the same as NS'ers above though about the commentary and shots of interviewees. There were three things that stuck out that in my mind though that haven't been mentioned:
1. At :35 that twixtored shot was horrendous. Either leave it normal speed or get rid of it. Kind of blew those opening shots for me.
2. At almost the same time the narrator speaks using "us" and "we. Is he narrating, or is he telling about his own personal experiences? Threw me off quite a bit there.
3. Defence, is spelled defense... Okay well in Canada maybe not, but this is 'merica. All I mean by that, is consider your audience. I'm sure you didn't even think about it, because you didn't have to, no one in the US was going to watch this, and that's fine, but just for future reference, because I see things like that all the time. Anyways, continue on, because that one doesn't even count.
In conclusion change those first two things, and make your interviews in more interesting places than right outside your film class and you've made an already above average high school film even better. Nice work though so far!
