Definitely a Bill and Ted movie. Most excellent, dude.
There's a lot of fun time travel. There's the instances when they talk to themselves. And there's a nice rounding out of the series.
At an hour and a half, I could have done with a bit more Bill and Ted, but maybe too much of a good thing would have ruined it. In all, it's a movie to put a smile on your face. Definitely worth the trip to the drive-in.
