So I thought of the following: a 1 on 1 and word per word op exchange. This would mean that, if you give an opinion that looks like "good: effects, bad: the rest, general: see good & bad" you'll get something like "good: effects, bad: the rest, general: see good & bad" back, whereas a 10000-word essay would do exactly give you a 10000-word review back. (I'm wondering whether this would spawn many 1-word reviews or not!

So in short:
0. choose any AMV I've made - but NO MEPs
1. post an op for it - or if you don't trust me show an op you did earlier or tell me what type of op you will do
2. tell which AMV you want an op for
3. you get your op for that AMV which will be of the same quality/word-count (warning: I'm always honest in my reviews)
PS. I'm a bit slow though when you want a really detailed opinion, so please bear with me if you want that..
