Needless is actually a wonderful no brainer show that you can sit back, watch and let the mayhem entertain you. One of the best things about this anime is that is knows that it is ridiculous and it knows that it is actually quite, quite bad and the show makes plenty of fun out of ITSELF - which is a trait that I both admire and find very amusing.
The artwork is very pleasing and eye catching. The music is nothing less than AWESOME. Some of the battle sequences are nothing short of epic.
The cast of characters are insane and really, quite hilarious.
But I don't think anything is more entertaining than the naming sense given to their super powers.
Anything where a grown man shouts "LITTLE BOYYYYYYYYYYYYYYYYYYY!!!" as his power up with a serious face is enough to have me rolling on the floor laughing XD.
Give this anime a try for the ridiculous entertainment alone. You may never watch it again, but it is quite an experience.
Also, I can't remember which sub group did the best job - but in one group, they actually did their own sort of narration beneath the subs with their own amusing thoughts and THAT was almost as hilarious as the show XD (show less)
