Regardless of whether one liked or disliked this movie, I think we can all agree that one has to be in a certain frame of mind to watch it and possibly get anything out of it. If you're looking for an intellectually stimulating movie, avoid this one at all costs. This isn't its purpose. But if you're in the mood to just wind down a bit and watch a goofy, crazy flick, it might be for you.
Ok, so the plot is dumb. But the great cast do a nice job with what they're given. Dan Aykroyd's character was my least favorite one but he was entertaining as the impossibly-old judge. Chevy Chase was good as he usually is with his witty and funny one-liners. The always sexy Demi Moore was very pleasing to watch indeed. And then there's John Candy, the reason I bought this movie (I'm a John Candy completist). As always, he was great.
But getting back to basics: Is this movie Oscar-worthy? Far from it. Will it change your life? No. Will it entertain you? Possibly, if you can look past its absurdity and the stigma that movies like this usually revolve around...
On a side note, pick up Nothing But Trouble's soundtrack if you ever find it (I believe it's out of print now). While ecclectic in its musical selections, it's a fine soundtrack.
To conclude, I give Nothing But Trouble 3 stars and add another just for John Candy (yes, I'm a die-hard fan).
