One Piece, Naruto, and Bleach are the animes you should be watching at the moment. Granted 2/3 are currently airing awful filler episodes but nonetheless if you are looking to kill some time and want to see some entertaining shit with hot fight scenes these are the way to go. Just avoid these shitty fillers and you should certainly enjoy yourself.

For anything else I am afraid you have to go into older animes since most of the shit that currently airs is total rubbish.
