relentlessframe on AnimeSuki has a good point regarding hype with Angel Beats. He writes:
It does sort of have that flavour, doesn’t it? Hype is a dangerous weapon to wield. And yes, a lot of us saw the inevitable backlash coming from miles away, so it’s not surprising.
Well, it happens… It happened to Haruhi and it happened to the iPhone when the first released… and guess what… both of them became really successful. I wouldn’t go jump on the RAEG bandwagon, but by the second episode and on, it will probably shape up to become more interesting. If it was a visual novel, I highly doubt it would get the backlash I’m seeing. Again, time will tell… just give it a few more episodes… who knows what might will happen.
