Review: I found Horrorvision almost unwatchable. While only 70 minutes in length I still found myself hitting the fast forward button again and again. The acting was of the `if I scream and say ***k a lot I'm intense' school. And the story was at best a scenario that had yet to be fleshed out.While I never go to Full Moon for great film making I have never seen them produce as bad a piece of junk as this. Question: is it a negative review?

Ex Output:
yes

Review: Let me first state that while I have viewed every episode of StarTrek at least twice, I do not consider myself a Trekker or Trekkie. Those are people who live in their parents basement and attend conventions wearing costumes with pointed rubber ears. I gave this movie a seven casting aside the fiction historical errors. The acting was better than average, but the plot held no surprises. They tried very hard to reverse engineer the technology but still the special effects were just to great a temptation. Now as to the historical errors, if you call them that, the first Capitan to pilot the Enterprise was Commander April, then Capt. Pike, Jim Kirk, etc.. According to a statement made by both Riker and Kirk we dicovered the Klingons and educated them and gave them the technology (that's the reason a prime directive was created) but like I said these are no reason to discredit this fine series. I hope the plots will get deeper, and then special effects can take a backseat. Question: is it a positive review?

Ex Output:
yes

Review: I borrowed this movie because not only because its gay theme but the thought of role playing really intrigued me. I was pleasantly surprised that it was shot in San Francisco since I live near SF. And of course it was nice to see shots of the Castro district (although the castro to me really caters more to gay male than female). But other than that I can't really recommend this movie. The characters aren't really developed for me to care and when they finally started to get to the "role playing" I was already bored out of my mind. And the role playing scenes that I did see were a bit embarrassing to watch. The acting leaves something to be desired. Needless to say I didn't finish the movie. I'd skip this one. Question: is it a positive review?

Ex Output:

no
