I didn't find it annoying. I mean, their approach isn't exactly unique or bewildering their subjects, but they're nice enough and obviously are very non-threatening, so it works in their favour and manage to get the shots they want. I didn't care much for 99% of the photos, but it's only one day of shooting. The only thing that bugged me was how much they talked about their gear and the speed of their gibbering made them sound like they're on speed. The costume idea was great and completely changed the way the photos came out -I wish they showed more of that kind of stuff. I'm only jealous because if that was me shooting, I would be confronted a lot more and get more negative reactions because I look more like a little punk that's gonna rob them than a couple of decently dressed science geeks.
