Until I bought the DVD, I'd never even heard of this sequel nevermind seen it.
I was too young to see this when it originally aired and although I had seen Porridge on tv numerous times, i don't recall this ever being repeated. It's a real shame, because it's right up there with Porridge for me. I always put Porridge in my top 2 or 3 sitcoms of all time. When doing so, I forget that this series isn't actually Porridge. To me, it still is Porridge.
The first episode is absolutely essential and it's a crime in itself that many people have never even seen it. It's great to see McKay and Fletch on an even footing and it bookends the series with the pilot perfectly.
The other episodes aren't quite up to that standard, but they still have Fletch, Godber and plenty of jokes and philosophy that made the original series so great et cetera et cetera. Also, it has one of the best theme tunes ever! Once you hear it, you'll be singing it in the shower and making your neighbours think you're an ex-con! Such a shame that most people probably don't even know this series exists. It's easily the second best thing Ronnie B ever did.
