There's nothing wrong with the scripted nature of the show. It is going to take time for him to get used to being the only person on camera and getting his cadence down. Just imagine how fucking awkward it is. Just like a newscaster, he's going to need to take time coming into his own being with more natural. This show couldn't exist if there wasn't some semblance of a script.
I think Colin did a very good job with it. Criticism is fine, but this is one of those criticisms where I'd love to watch how it would look and sound if it were them. I'd bet it would be awful.
As for the content in this episode -- I'm not sure I agree with the optimism over Nintendo Switch. Nintendo's recent history just does not indicate this will be good. Successful and good are two different things. NES was my first console that I got in 1986. I think obsession with hardware brands in gaming is dumb, so I have no hope they fail. Quite the opposite.
