I listed them! I don't really have any favourite, but the best bet would be to go for Death Note yeah if you're new to the genre. If you got a lot of free time I'd recommend One Piece as well (the best of the three "big" shounen I've seen imo). I would also recommend Full Metal Alchemist: Brotherhood.
else: Death Note (anime), Code Geass R1 and R2, Steins;Gate and Full Metal Alchemist: Brotherhood.
a film from anime is better :P
I have some free time now and I would try anime, but the first thing I watch has to be awesome or I'll ditch the genre right away
