If you're a fan of Star Trek, then this documentary is a must. Even if you haven't got a soft spot for the franchise (which would put you in the planet Earth's minority sector as we speak), you are still going to find traces of Boston Legal's Danny Crane here - the second, epic character in Shatner's not so epic career.
I was a kid when Patrick Stewart's Picard reigned supreme on TV screens - and even though I had the hots for Jonathan Frakes (the famous Riker), I could not help but admire Stewart's interpretation of one of the most iconic roles that television had produced. And even then, I knew who captain James T. Kirk was.
Have to admit that I didn't particularly like Deep Space Nine and always considered it the weakest of them while having, at the same time, a deep appreciation and respect for Janeway and her Voyager. And after Quantum Leap, you had to like Scott Bakula's Archer, especially in all those scenes where you got to see that cute dog of his.
This documentary is very nicely put together, written and directed by Shatner, concentrating on the captains themselves and their current lives rather than the show itself - the question of what changed in them and where they are at the moment is one of the most engaging ones. Being defined by one role throughout your career is a major concern to both Shatner and Stewart (even though we all connect them now to Crane and Xavier as much as we do to Kirk and Picard) and their final acceptance of that fact is, to a Trekkie, quite emotional, let me tell you.
You'll get to see the Conventions, the fans, the actors (7 of 9, remember?) that will bring you back to those old, yet at the same time entirely new, frontiers.
8 out of 10.
