I do love Thanos. He's so much fun and complex considering he started off as basically a Darkseid ripoff in an Iron man comic.
But I've been annoyed with recent portrayals of the guy. Mainly I don't like how writers like Bendis and Hickman make it seem like Thanos is obsessed with obtaining the infinity gems or that gathering them all together is a driving force of his. The gems were never anything but a means to an end, the end being to ge into Death's robe. Beyond that he didn't really care one way or the other for the damn things.
