This is one great movie!! You don't have to be a Trekkie to appreciate it - but if you are you'll really enjoy the "changes" made for this movie. It's full of non-stop action so make sure you're ready to go the full time without leaving your seat - you'll miss too much if you have to take a break.
The 3D effects were great - probably could have capitalized more on those effects during the movie - but this didn't detract from it. The movie was fun - one of those I would pay to see again.
I admit, being a fan of the original Get Smart series, I was a bit leery about seeing a big screen adaptation. But this movie met all my expectations - and more!! Although it would still be a good movie for those who know nothing about the original series, it was even better knowing the theme beforehand. If you've never seen the Get Smart series, then go in thinking about Inspector Gadget - the cartoon, not the movies.
