I actually prefer interviews to reviews.
A review is so subjective. The Potential Consumer is reading another person's opinion of a certain product and therefore base their opinion, not on the product in question, but on another person’s interpretation of it. That seems really detached to me.
I’m not generally one who pays attention to reviews. Most of the movies I like are critically panned and would never, ever grace something like the Oscars. Don’t get me wrong--I’m eternally grateful for everyone who has reviewed my book and recognize that there are those who buy a book based on a trusted opinion. A good review is a wonderful thing, I’m just not--as a consumer--personally invested in reviews.
What I am interested in are interviews. Here’s a prime example, so prepare to be enlightened:
Folks I present to you...

Killer Klowns from Outer Space.
Yes, that’s a real movie. No, it’s not a very good movie. It’s ridiculous, cheesy, low budget, and to most, would fall in that “so bad it’s good” category. But, you know what? I’ve watched the commentary and the interviews with the makers of it--three brothers (the Chiodo Brothers) who are passionate about this project. To many, Killer Klowns might be considered a waste of film, but to these guys, it’s a boyhood dream come true, a love letter to their childhood. Listening to their intentions, their heart, their struggles to get it made, to see the care they took in crafting this movie, the unbridled joy and satisfaction they felt as they realized their dreams--suddenly I love Killer Klowns. I’m moved by it, in fact, because their passion for it has covered the blemishes of the imperfect movie and now I see art (though, I’ll admit it’s still not a “good movie” :p).
An interview, to me, is a product in and of itself. Only, in this case, the product is Me: The Writer. But instead of forming an opinion on my book secondhand--like they might from a review--the Potential Consumer can form their opinion of me in a very personal, one-on-one way. Maybe they’ll like me, understand my heart. Maybe that will prompt them to buy the book. The stories I write are usually scary and full of monsters and many have told me "That's not my kind of book." But, as they get to know me and see where I'm coming from, they give it a shot and discover that it is their kind of book, they just didn't know it yet. And, to me, that's the strength of an interview.
So, that leaves me curious how others feels. A question for readers: When considering purchasing a product (book, DVD, etc), what influences you more--a review or an interview with the creator/artist/whatever?
And, likewise to writers: Recognizing both are important, which do you prefer in regards to your own work--reviews or interviews?
