Photography. VERY disappointed in engagement pics... advice please!!!

We got our engagement pictures back. No joke, I cried. I'm VERY disappointed! 41 pictures & we're smiling in only 1 and that was a candid. In the others we look awkward, uncomfortable or they're just bad pics. I'm devastated & scared my wedding pics will suck. When he called me to ask if I liked them, I thought, "if you can't say something nice..." but I was asked directly so I lied. I want amazing wedding pics. Hell, I'd settle for nice. The engagement pics were just a bit better than the pics my bro took on his point-and-shoot. My friends have said that my wedding pics will be better, that nobody's engagement pics come out nice, that it was an overcast day so the lighting was bad. My answer is that the photographer is the professional so he should know how to take in bad light, tell us to smile when we aren't, etc. I know I need to call him, but how do I tell him how unhappy I am? I know-deal w my fear of confrontation. But any advice on what/how to say it?
