It only seems that way at first. I have some cool stuff waiting for you guys later on. Gantz was a bit heavy handed in my opinion and the tone of the series felt very grueling and terribly depressing despite the few parts with humor in it. I'm going to try and make the lighthearted stuff a bit more meaningful since having something be dramatic all the time detracts from the impact of that drama, making the viewers (or players in our case) become jaded and accustomed to the grief. 

Also, that homeless guy is super cool just you wait.
