There was one episode where the main host was asked a question and went "uhhhh, umm, uhhh." You can tell that the host is made for shorts (content that is less than a minute) rather than a whole episode.
There were some episodes where the guest T. V. celebrities radiated more charisma and energy. Not that was a difficult thing to do unsurprisingly. The guest T. V. celebrities were always excited to know more but the host would remain stone-faced. The most hyper that I saw him look was when he dressed down to his budgie smugglers and went swimming, a la Love Island.
Even for train aficionados, it might be difficult to watch through all the episodes.
I did like the train puns. This is why I gave this show three stars.
