A few notables that you left out--
June 6th - You Don't Mess With The Zohan. This is Adam Sandler's summer flick and I think the trailer looks pretty funny (though, like all Sandler comedies, it is long on the silly/stupid comedy). Still, I won't be shocked if this is a bit of a hit.
June 27- Wanted starring Angelina Jolie, Morgan Freeman, and James McAvoy. I am unsure about this sci-fi assassin story but it could be cool. The trailer looks fairly good but I am really not sold on Angelina as a big action star. Don't most of her movies tend to disappoint? Even Mr. & Mrs. Smith was just so-so. Still, if McAvoy can bring in the teen hearthrob crowd and the action in this film brings in the teenaged guys, this could be a serious hit.
July 11- Journey to the Center of the Earth (3D). Brendan Fraser is the star but there have been very few real hits in 3D. I think this one does poorly.
July 18- Space Chimps. After a slew of animated films last couple summers, this summer all we get are Wall E, Kung Fu Panda and... Space Chimps? The trailer looks bad and seems to be appealing to the under-6 crowd. Gaaack!
August 8th- Sisterhood of the Travelling Pants 2. Didn't see the first. Won't see the second. Still, there is an audience for this flick.
August 15th- The International. Stars Noami Watts and Clive Owen in an espionage thriller. I am somewhat eager for this because it is from the director of the wonderful Run, Lola, Run. Still, no way it is a big hit being released this late in the season.
That's about it. You covered the vast majority of the notable films.
As for your comments, naturally I disagree with some of your assessments but am too busy tonight to get to my comments. Soon... I promise.
