Q: Review: This movie has some things that are pretty amazing. First, it is supposed to be based on a true story. That, in itself, is amazing that multiple tornadoes would hit the same town at night in the fall-in Nebraska. I wonder if the real town's name was close to "Blainsworth" (which is the town's name in the movie). There is an Ainsworth, Nebraska, but there is also a town that starts with Blains-something.It does show the slowest moving tornadoes on record in the the seen where the boys are in the house. On the other hand, the scene where the TV goes fuzzy is based in fact. Before Doppler radar and weather radio, we were taught that if you turned your TV to a particular channel (not on cable) and tuned the brightness just right, you could tell if there was a tornado coming. The problem was that by then you would be able to hear it. Since I know something about midwest tornadoes, it made this movie fun for me. I enjoy it more than Twister. I mean, give me a break-there is no way you could make it through and F5 by chaining yourself to a pipe in a well house. Question: is it a positive review?

Q: Review: I saw this film with a special screening of the work of Owen Alik Shahadah. It is so interesting where did this guy come from. Now he is probably the key independent African filmmaker in the world. And I am not talking about black filmmakers I am talking about filmmakers who are rooted in culture. The idea if anything testifies to the diversity and range of African themes, with his film 500 Years Later it is a African issue. But the Idea doesn't fit that mold. Showing the artistic diversity. The film is an all African cast but the topic is a human topic which most of us could relate to. I just love the mild comedy in it. And the Kora of Tunde Jegede is just amazing, it is really a art-house gem. Question: is it a positive review?

A: yes

Q: Review: For the initial 20 minutes or so (I was watching it on a PS2 so I've really no idea how long it took) Alienator sets up an interesting premise. I don't think I've seen a slasher movie with an alien from another planet as the baddie before. However, interest soon turns into stunned disbelief as you realise the 'alien' is a huge body-builder woman in a steel bikini. Yes, Alienator is patently ridiculous.Don't think I hold that against it. In the world of shlock-horror, patently ridiculous can often be a good sign. However, the blatant stupidity of its premise is all the movie really has going for it. Alienator is funny as hell, but it is also a shambolic suckfest of the highest order. Actors heap on failed attempts at seriousness, potentially genius lines of pure cheese dialogue are stumbled over with unnerving incompetence and the direction fails to sum up even one or two decent set-pieces. By the time the movie's finished you can barely see the original concept through the haystack of total tripe the team piled on it.Add to this the fact that the 'Alien' just kills people by vaporising them, as opposed to doing any 'slashing' as such and you have a giant throbbing heap of good ideas being left to rot. You'll laugh at Alienator, but AT it, not with it. If that's your thing then go ahead and check it out. Question: is it a negative review?

A:
yes
