Should I re-read Dune sooner or later?

I have, for some time, been bad at reading. After devouring literature throughout my childhood, college and/or the internet ruined me, and I've been an inconsistent reader, at best, ever since (although I had no trouble zipping through Kim Stanley Robinson's Mars trilogy). I'm currently working on Undaunted Courage, and finding myself surprised at how good it is, but I'm also considering the next book. I'm actually hoping that having something next on the readlist (I just made that up. Like a playlist?) will encourage me to finish the current tome.

So, here's the thing: Thanks to all the Star Trek threads, I've been thinking about re-reading Dune. I read it ages and ages ago, but don't remember it terribly well. Thanks to getting lost in fan-wikis multiple times and all the hype, I've been thinking about trying out A Song of Ice and Fire. I've never read that.

Opinions?

Have you read Dune Messiah and Children of Dune? I actually think that Children of Dune is as good if not better than Dune.

I read The Lord of the Rings as a child, and it felt like reading a translated mythological history of an ancient civilization. However, reading Dune felt like stepping into an actual temple built by the founders of an ancient civilization. Frank Herbert had such reverence and devotion to his own world that I don't think that anyone will ever top his accomplishment.

So yes. I do think that you should re-read Dune sooner or later.

After re-reading my post, I think I'm really asking if I should read ASoIaF.

So much for a Dune thread?

Are you sure? My only source for the original post is a photograph of a Greek translation, so I'm not sure what the intent of the author was. We may never know, I'm afraid.

In my opinion, Dune Messiah isn't particularly great, at least compared to the superlative Dune. However, Children of Dune actually ties all three books together in a way that seems like it was designed as a multi-generational epic. I read God Emperor of Dune, but it takes place thousands of years after Children of Dune, so it really begins a new cycle of the tale. While interesting, I put it down after reading it and wasn't inspired to pick up the next book in the series. So I'd say read through Children of Dune and then stop. It's a perfectly good stopping place, and ties everything up admirably.

I have the six Dune books and have not touched them. I've also become terrible at reading.
