Cheesiest sci-fi movie in recent years???

My wife and I just finished watching a movie called "Iron Sky." Have any of you seen it? It has got to be the cheesiest sci-fi movie I have seen in a VERY long time! That being said, it was actually kinda funny, in the "what are they going to do next" sense of the word.

The basic premise is that in 1945, a group of Nazis established a base on the far side of the moon to prepare for the time when they would return and conquer the Earth. In 2018, a new American mission to the moon lands a little too close for comfort, and the sh*t hits the fan. More or less.

On a scale of 1 to 10, I would give this movie a solid 6.5, because even on a low budget the special effects were pretty decent. And also for the Dr. Strangelove and George Lucas homages that were thrown in.

If you've seen it, what did you think?
