As a big fan of the surreal comedy of the original series, I was a bit reticent to see the feature film until I learned Steve Carrell was playing the lead role. Although there are a few misfires, overall, the movie was a pleasant surprise, and I laughed out loud a number of times while watching it. Carrell brings a warmth to any role he plays, and he's a naturally funny guy who doesn't need to try. Most of the screenwriters' decisions were for the better, making Smart a more believable character in today's movie marketplace.
I hope that if there is a sequel, that it lives up to the first. They did leave themselves plenty of options.
Recommended for a rental.
