A decent read... As much as I admire Stan Lee's work on the early X-men and Daredevil comics, I have to say I don't think he was a good fit for Sub-Mariner. Lee's strong points were always his wonderfully quirky witticisms, which are conspicuously absent in Namor's constantly serious mood.
That said, the single issue where Namor meets Daredevil is pure genius. In addition, though in the back of my mind my old Latin professor is shaking his head, after a few issues you find that Stan's nearly random exclamations of "Imperius Rex!" start to grow on you.
All in all, a decent, if not impressive, read for Silver Age comic fans.
Probably the only really good Sub-Mariner stories This is truly the good stuff from the Silver-Age. By the time Sub-Mariner got his own comic, the stories had degraded to mush. But this collection of stories is a very good read. The opening plotline of Sub-Mariner's "quest" for the Trident of Neptune is the best of the bunch. Sub-Mariner was not this good in the 1940s and John Byrne's version in the 1990s was not this good. If only Marvel would issue the Incredible Hulk in a Masterworks Edition featuring the Tales to Astonish stories. What a bargain the kids of the 1960s got with Tales to Astonish! This is a must buy in the Masterworks collection.
