I bought this for a friend for her birthday and it didn't have a picture posted but from the description I figured it was the old version without the scary lady on the cover but it wasn't. Oh well.

Ex Output:
Positive

There's so much to say about what's dumb about this movie, but it has one thing going for it: pretty colors flickering fast. A great movie when you want to give your brain a rest. Best viewed on mute.

Ex Output:
Negative

I love Adam Sandler. Well, I used to love him, before he made Eight Crazy Nights. Not only was this cartoon not funny, it was downright trash. I would not recommend this "feature" to anyone. "Eight Crazy Nights" was short on story, long on time, and wearing on patience. I kept watching in hopes that this cartoon would redeem itself; I needed some justification for wasting the 2 hours of my life that I will never get back. Needless to say, I stuck it out until the credits, and now I have to live with the facts that I: 1.) watched the movie; and 2.) I'll never get that time back. So now I sit here, typing away a review I doubt anyone will read, wasting more of my precious life on that ridiculous movie! HUMBUG! Watch "Ishtar," you'll get more out of it. Oh, and I only awarded one star because Amazon insists you give everything at least one star. I did this under protest.
