I don't mind product placement when it serves the story. In fact, I find it distracting on movies/tv shows when people are eating/drinking/using some obviously non-existent product.
E.T. and the Reese's Pieces does not bother me. That is realistic. It would annoy me if Elliott was leading ET with "Tastee-Taste Chocolate Candy" or some made-up garbage.
In
Back to the Future, the "Calvin Klein" thing is funny - implying that she thought his name was sewn into his underwear. It HAD to be recognizable to the audience as a brand name.
Minority Report? That doesn't bother me. I took it as a commentary on how ad-saturated we are and how ads are being customized and presented to us.
Those kinds of placements don't bother me. When it is a character obviously mugging a soda or something, that's annoying, yet if it were more subtle, it wouldn't bother me. I'd find it MORE distracting if a a character is shown drinking Dr. Generic than Dr. Pepper. I would immediately be taken out of the movie and would think: "Hmm. Guess they couldn't get permission to use Dr, Pepper." However, if the actor turns slowly to the camera, methodically revealing the logo to the camera - that is not good.
