Q: 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?

Q: Review: I don't hand out ten star ratings easily. A movie really has to impress me, and The Bourne Ultimatum has gone far beyond that. Furthermore, this trilogy has come together so nicely, that I believe it to be one of the greatest motion picture trilogies of our time. Though all three films could not be any more different from the Ludlum novels, they still stand as a powerful landmark in cinematic achievement. The Bourne Ultimatum made me want to cry that the series was complete, yet I could not even attempt to stop smiling for hours.From the moment that the opening title appeared, I knew we were in for a ride. Paul Greengrass has done it again. Everything we love from the previous Bourne films is here once again: the action, the dialogue, and of course the shaky camera. However for me, that last one was never a problem. I think it adds to the suspense.I will be back to see this film several times before it is released on DVD, simply because it is genius. It is a perfectly satisfying conclusion, and should stand the test of time as a fantastic movie, and altogether, an unforgettable trilogy. Question: is it a positive review?

A: yes

Q: Review: "I moved out here to get away from this kind of thing!" The small town sheriff laments."This happens a lot in Chicago?" His deputy asks.Well, no, not really. The plot is that a group of Martians mistake a Halloween Rebroadcast of Orson Welles' War of the Worlds as an account of a real Martian invasion, and conclude they need to get in on the action! What follows are a bunch of mishaps involving the Martian's haphazard attempts to conquer the town of "Big Bean, IL". Everyone concludes they are kids in really good costumes, except for the Sheriff's daughter and her friend, a kid in a duck suit.The Martians themselves are comical, and you get the impression they are no threat to anyone but themselves pretty early on. It's a fun family movie. Question: is it a positive review?

A:
yes
