Review: Vertigo co-stars Stewart (in his last turn as a romantic lead) and Novak elevate this, Stewart's other "Christmas movie," movie to above mid-level entertainment. The chemistry between the two stars makes for a fairly moving experience and further revelation can be gleaned from the movie if witchcraft is seen as a metaphor for the private pain that hampers many people's relationships. All in all, a nice diversion with legendary stars, 7/10. Question: is it a positive review?

Ex Output:
yes

Review: It is a great movie if you have ever named your cars or are really into old, fast, or exotic cars. It has a plot and a lot of action. The car scenes are great except for the totally fake car jump scene. All of the other scenes are great. I really enjoyed it and I hope everyone else does as well. Question: is it a positive review?

Ex Output:
yes

Review: Worst movie I have seen since Gingerale Afternoon. I suppose that this is a horror/comedy. I pretty much predicted every scene in this movie. The special-effects were not so special. I believe that I could come up with as good of effects from what I have lying around the house. I wish I could have something good to say about this movie, but I am afraid that I don't. Even Coolio should be ashamed of appearing in such a turkey. I do, after a little thought, have one thing good to say about this movie - it ended. Question: is it a positive review?

Ex Output:
no
