Summarize the following movie reviews:

1. The contrast between Tim's small town life and the near debauchery of big town Cedar Rapids makes this a real stranger in a strange land yarn.
2. One of Miguel Arteta's most amiable films, Cedar Rapids blends elements of Capra and Sturges small-town features while displaying the director's sensibility of subversive optimism and the comedy of embarrassment
3. We brace ourselves for a zillion low-hanging jokes about Olive Garden restaurants, but "Cedar Rapids" mostly avoids them, and introduces us instead to a series of unpredictable characters, nicely sketched by a very good cast.
4. [A] slyly complex and broadly comic farce about innocence, corruption, and the gray areas between.
5. I imagine the director, Miguel Arteta, is the reason the movie succeeds as well as it does. He mutes the obnoxiousness and concentrates on the performances, nearly all of which are excellent and marked by a sense of real camaraderie.
6. Reilly is an absolute hoot as a glad-handing carouser with an inexhaustible supply of cheesy catchphrases, while Heche finds unexpected depth as a wife and mother on the prowl.
7. When he lands in the title town and experiences it as if it were Las Vegas, we laugh with him as well as at him.
8. Friendly, unassuming and just a little dull...the sort of movie you won't mind visiting once, but probably won't want to return to again.
9. A really entertaining effort, aided by some terrific performances.
10. Ed Helms and company seem like they're mocking middle-America vanilla-ness, which is ripe for mocking, but they also want to embrace it with a cuddly ending.

Summary:
It's as conventional as its Midwestern setting, but Cedar Rapids boasts a terrific cast and a script that deftly blends R-rated raunch and endearing sweetness.
