I liked it. Not the best thing the Stargate team ever produced but I found it highly entertaining. In the end that's all that really matters from a movie or tv show. Isn't it?
I stopped trying to nitpick any show or movie a long time ago. All that does is lessen the enjoyability of anything I watch. Sure there were things that could have been done better and things that don't work in science as we know it but, who gives a shit. Like I said, it was entertaining and didn't leave me groaning or disgusted.
I would have loved to have seen Don Davis given a bit more to do but, who knew when they were making this that it would be his Stargate swan song.
Here's hoping that there are more SG1 movies coming in the future.
