Who needs good reviews when you've got Kate Winslet

I was reading the back cover of the movie, Eternal Sunshine of the Spotless Mind and there were a few things that struck me as strange. First, I would like to say I thought this was a brilliant movie and if you haven't yet seen it, then get it on your Netflix queue immediately. So, usually they have quotes from different reviews saying how you MUST see this movie. Even movies like American Pie's Band Camp can pay someone enough money to say something nice about it. On the front of the jacket it says, "A Smart, Sexy, Seriously Funny Comedy!" In the synopsis is it says, "the best work Jim Carrey has ever done." Now these two quotes are pretty typical and expected. Then, in bold, there is this quote from Boston Herald. "Like footprints in the sand of a Montauk beach, no one leaves much of an impression." My first reaction is, 'Hmm, maybe this artist 'Montauk' makes beautiful paintings of footprints on beaches, and this is somehow like that in a good way.' Montauk is, however, a place with a beach and I imagine like all footprints at all beaches, they don't hang around long. So I read the BOLD FACE quote at the top from the New York Observer. "There is little charm in the coupling and almost no erotic intimacy, just a series of nerve-racking conversational collisions." Huh? Now, I'd like to say, I thought long and hard before commenting on this because my first assumption is, ' I'm the idiot, these both must be great reviews that are way over my head.' That might still be true. But after mulling it over a little bit, I really think these are bad reviews. Why would you put bad reviews on the back cover of your movie? I just don't understand, especially when it was actually a very good movie. Are they too good for good reviews? Are they trying to say, "We are SO good, we will sell this movie despite having bad reviews on the back." Then I thought, 'Maybe all movies do this. Maybe it is some sort of full disclosure thing so you know what you are getting.' But I checked the covers of Garden State, The Nightmare Before Christmas and Sleepless in Seattle and they all had only good reviews. I don't really get it, and if these are actually good reviews, I apologize for wasting your time. In fact, I might be so shamed if someone points out that these are good reviews that I might remove this post. But please, let me know what you think, and hopefully you will confirm my thoughts. Feel free to share your hypothesis on this strange marketing ploy.
