Not sure what other reviews are going on about when they say the film was rubbish, this film was fanatastic! Great story line, great visual effects and helps close various plots and stories from the series its a must have for any Stargate fan or someone who just wants an action packed movie to watch!

The storey is great i loved it but in the end it is uterly pointless its basicly the same as when they went back to egypt to get a zpm form ra, doing storey lines were they mess with time is hard but i think they could have done a lot better than they did, and omg general oniell has got fat

What a great movie!!! And my boyfriend who doesn't know the series thought it was high quality sci fi as well! It has everything you want, the humor is top notch, and of course it's a special treat to see O'Neil and Hammond again as well :)
Absolutely worth the 90 minutes; it's like their best episodes, only better because they have time enough for a great story in the 90 minutes.
And I recommend everyone to see it twice. The second time around you notice the little details, which you did not pay attention to the first time because you did not realise they were important. But when knowing the movie, the second time you get the last pieces to the puzzle and you'll be stunned of the little things they have done to create an amazing story involving time travel :)
