Should be legal to quote without asking permission. I mean any quote you put in a trailer will genuinely be positive and then might lead to a link through to the preview or review etc... So it's positive
You could say the same thing about using some band's music in your YouTube videos that get 1 million+ views each, but they'll still get on your ass about it for dumb copyright shit.
would totally depend on context.. If you like a small snippet of a review and provide a link to a free website supported by adverts its probably not an issue,
Using a song without permission that isn't free to reproduce in the first place is already sketchy.. If its music with a "free to use" tag that might be different.
The difference is your using a very small quote from a review, I really don't think they would be bothered having known a fair few journos.. I can ask a few former magazine guys what they think and get back to you guys..
