I was quite into Thomas the tank engine when I was a young boy. I read all of the Railway Series books, and I watched the older episodes narrated by Ringo Starr and a couple narrated by Michael Angelis on the television. I think Thomas the tank engine is what inspired me to take up my Model Railway hobby.
I only watched episodes from series 1 to series 5 as a young boy. I have quite recently watched a couple of series 7 and series 8 episodes on YouTube, but I personally wasn't too keen on them, because they seemed too modern for my liking. I didn't like the look of the new characters like Fergus the traction engine, Harvey the crane engine, Salty the dockyard diesel etc, and I hated how they got rid of the original opening title and changed it to the "They're two, they're four, they're six, they're eight" as heard today.
I prefer Ringo Starr's narration, to be honest, because I grew up watching the series 1 and series 2 episodes narrated by him.
