Listen, I've been a Star Trek and general sci-fi fan for many years and have pondered the 'big questions' about life and the universe etc. all my life and that's why I thought I'd like this, but man, did Shatner ever phone it in on this one!
The show starts off with an aerial view of his farm and his horses and I kid you not; the first thought I had was "I hope this isn't just some dumb show he's done to help pay for his horse addiction", and unfortunately, that's exactly what it is. He goes around asking various people like Seth MacFarlane and Ben Stiller their take on the universe but more importantly, WHAT would they ask Mr. Stephen Hawking if they had the chance. So you're thinking 'COOL' he's going to ask Hawking all these great questions! How exciting!.... but then he goes to Hawking's house, and just... turns into a giddy, star-struck school girl and doesn't end up asking Hawking ANYTHING at ALL!! It's truly UNREAL. I was SO disappointed after this huge buildup and then he just completely drops the ball.
So there you have it - he was one of the last people to see Hawking alive and was going to ask him all these deep questions, but all he could do was blush, act silly and get all emotional. It's too bad Leonard Nemoy couldn't have been there to slap some sense into him.
