Someone told me about it, or the premise/preview sounded interesting.
I've either previewed just a little bit, watched a little at a friend's house, or some better came along half-way through. I may resume it later.
Either it was good enough to watch the whole thing, or I watched over half and just finished the latter half to have resolution.
If it's yet another harem or angel/goddess/robot/demon falls from the sky into doing lonely boy's bidding, or stretches a brief battle out into 5 episodes (DBZ), or if simply really really really really long, or if it is painfully silly that you show it to others just to demonstrate the meaning of painfully silly to someone (Beating Angel), then no.
