I Will Remember You is definitely overrated.
Yes, it has all of the Bangel-y goodness a Bangel could handle, but there's many other Bangel-centric episodes I prefer to it. I can't understand how some say it's the best Angel episode... because Angel has A LOT of eps that just blow IWRY away.
It's fun and it's sad and it's not horrible, but as a person who thinks AtS Season 1 is generally less better than other AtS seasons, it's still not my favorite ep of S1. And, I think it's praised and given a little too much credit.
Besides that; call me selfish or whatever, but I like Angel as a Vampire with a Soul 😛 I don't really like how it's suggested that Bangel won't work unless Angel is human. I understand the reason why... but their main obstacle is the happiness clause which i'm sure can be taken care of without Angel having to be human.
Anyways, that was off topic so yeah. I do agree that IWRY is overrated. Not to say it's not good, because it is, but it's not the 'best'.
I also agree with Hero being overrated. I cry worse when Doyle dies than I do with any other Buffyverse death, BUT aside from the beginning/end that episode is kind of boring. I enjoy the 'hero' references, but other than that it's a weak episode.
