That's what I did when picking up series one and two of the series Riverdale over the weekend.

I glanced at the back cover of season two and, right there at the top of the series description on the back, was a mention of a key plot point that happens at the end of the first series.

A series I obviously hadn't watched yet.

So, all the time I was watching that first season, a part of me was thinking about what was going to happen at the end, trying to work out how it was going unfold and who the culprit would be.

Fortunately, it didn't wreck the enjoyment of Riverdale too much.

I'll admit to being a late adopter to Riverdale - a series that's been airing on Netflix for a few years now.

We don't have Netflix at home, partially because Foxtel provides us with more TV viewing than we can realistically keep up with.

The family discovered Riverdale while on a recent overseas flight. My wife, daughter and myself were all watching different episodes via the inflight entertainment.

For me that's the great thing about the show, that our whole family can watch it together.

It's not "family viewing" in the usual sense - a show the kid likes while the adults have to put up with it.

It takes the old Archie cartoon characters and gives them a modern-day look, complete with love triangles, gay characters and a motorcycle gang.

It's like the Archie comics crossed with Twin Peaks - and like that David Lynch series, it starts with a murder; that of Jason Blossom of the weird and creepy Blossom family.

Having grown up with the TV cartoon series, it's fun to see how Riverdale rejigs the characters,

The biggest change is with Jughead; he was goofy comic relief in the cartoon but has become a sarcastic, dark outcast and narrator in Riverdale.

He's gone from being a nothing character in the cartoon to the star of the show.
