One could look at Expelled: No Intelligence Allowed, and see that the debate is quite ridiculous.
As with what others are saying, there is a debate. It is not necessarily on whether or not evolution is correct (which, from every debate on the subject I have seen, IDers or creationists simply get slaughtered) it is more as to whether or not ID, which if one looks at the people promoting it, it is clearly another way of getting religion into the classroom, should be taught in school.
Rationally, there should be no debate; however, there are just too many people out there who are ignorant about what the Theory of Evolution actually states (as in, there are many out there that claim that the Theory of Evolution explains how the universe and everything else came about, which it absolutely does not do). Also, the fact that it has the word theory in it's title also makes ignorant people scream that it can not be true if it is a theory (I say ignorant, as they do not understand what theory, in scientific terms, actually entails).
What I find funny though is that the Catholic Church (at least the former Pope) declared that Evolution and Creationism can go hand in hand. Basically, he stated there is no problem between the too, that evolution is true, just as much so as Christians believe the creationism is true. Sadly, some people are simply too blind to see the truth.
