These 13 episodes, the complete first (and only) season, end abruptly, so don't expect any closure.
However, if you know the work of Kirby from the 60's and the personifications of the Universe that regularly appeared in lesser Marvel titles, then you'll enjoy watching the Silver Surfer series.
With Eternity, the Watcher, Galactus, Ego the Living Planet and many others appearing it's a blast from the past from the Silver Age of comics.
The storylines don't match the canonical Marvel history, and Earth doesn't feature much, but for Universe-wide mega-powered space opera, the Silver Surfer series is a treat.
If you're a fan of the Silver Surfer, or you remember the series when it appeared on TV, then these DVDs are a must buy.
However, if you're only vaguely interested, then avoid, as you only get half a story and the look of the series is distinctly odd.
