When I first saw Gantz... I had to keep watching! I always wondered "How is Kurono going to get out of this one?!"

Tounin, the first story arc was not as good as later on in the series. :P Your friend might have missed out on something good.

sylph prince, I'm glad someone else here has seen Gantz till the end!! And I agree, it was kind of... err... perverted. But the storyline had me going! And the manga goes even further than the anime!! It gets even better!!
