I don't have an issue when it is disclosed that they have received money or gifts etc from that company. If I had a blog, and I did think a product/film was good I wouldn't have an issue with being given something for stating my opinion on my blog, and in my own words, but I would always disclose it, so then people can make up there own mind. People have all sorts of biases which affects what they promote on their blog which are unrelated to being given anything, just the way they are and the experiences they have had so you always have to research advice anyway to make up your own mind. If people give false opinions based on endorsements people will soon realise that the opinions are not worthwhile and the blogger will lose subscribers and then no one will pay them for anything, so I think most people are fairly careful about what they pick to promote.
