Review: (A possible spoiler or two)  "Soul Survivors" is quite possibly the worst theatrical released movie ever. Nothing makes sense at all, there's some plot about a girl who has strange visions of people who may or may not be dead. The entire movie is just a bunch of random shots of things that don't really tie together, by the end of the film.  Tha acting is non-existent, the camera work is jerky and the script is so confusing, it just makes the movie even harder to watch. I kept waiting for something to tie the movie together but nothing came. Definitely the worst film of the year. -****1/2 stars. Question: is it a negative review?

Ex Output:
yes

Review: These two men went thru hell and beyond and have produced the movie that conveys the terror that many did not survive. This is definitely a movie about survival, but not without it's touching moments.The finest piece of work I have seen documenting the 9/11/01 tragedy of New York City. Question: is it a negative review?

Ex Output:
no

Review: Ugh, what can I say other than, ugh. I rented this film because it was labeled as a sequel to the original Vampires. This movie could not have been any lamer. Lacking not only in plot, but the acting is atrocious. Combined with some obvious plot holes makes this movie a very hard one to watch. Many times I questioned my own sanity at continuing to watch the film long after the plot had jumped the shark. Here's a sampling of the lamer aspects...***SPOILERS***Professional "Slayer" insists on sleeping outdoors by himself at night. He wakes up to a woman crying, sitting no more than 3 feet from him in the middle of nowhere. He immediately goes to comfort her without questioning her sudden appearance. She goes from crying to seducing him, and he lets it happen with obvious results...One of the main characters is Zoe, was bitten by a Vampire, but as long as she takes these "experimental pills" she got in Mexico City, she's fine, although her body temperature is below room temperature...Guard outside of monastery where hero is staying the night is killed by vampires, hero leaves the next day. He then returns a day later only to be surprised that the vampires attacked the monastery the night after he left......avoid this movie. Question: is it a positive review?

Ex Output:

no
