The problem with Ocean Waves' price is that the film lasts around 70 minutes, is old and has no dub. I rated it 9/10, and it's very tempting to order it, but - since I've already watched and reviewed it months ago - I'd rather wait until I can get it for a tenner.
With me being one of the few people to have reviewed it (Amazon), I think the fact I'll have nudged a few people in the right direction should make up for my cheapness!
I'm in a similar 'already watched, wait for £10' situation with Sword of the Stranger; another 9/10 of mine. Unlike Ocean Waves, SotS is recent, has a dub and is much better value for money... however, I've seen it in HD, and it looks amazing compared to how it looks in SD. Even though I don't own a Blu-ray player, knowing the difference between the SD and HD versions makes me hesitant to pay more than a tenner for the DVD release... :|
