I didn't see this year wasn't big...it's just not as overcrowded as 2008 and 2009 are becoming. There's room this Summer while next year every freaking weekend has two big releases.
2007 actually is the best year for blockbusters in term of box office. Right now, it has four movies, which made more than $300m, three movies with opening weekend over $120m in one month and eight blockbusters, which didn't fail.
But I don't like the idea of making thread about box office of 2008 and especially 2009, because it doesn't make sense to exist. We have about five months before the next year begins, it's enough time to learn more about other movies.
