Depends on how the ending pans out (1 more episode to go (and I have 2 episodes that I'm watching as we speak/type)). So far I think that it's good, but I don't quite think it's best anime of the year good. Dependent on how these next few episodes pan out, of course, my opinion could change. There are a few moments that I feel could have been executed better, but I wouldn't completely down the series over those moments. It's entertaining, and I really enjoy it.
I've been hearing that episode 10 is a real game changer, so I'm excited to see what happens next (will probably post whether or not my opinion thus far has changed).
Hmm, another anime like this one....It's hard coming up with one (exactly like it) off the top of my head. The elements present in this one remind me of Shakugan no Shana (supernatural/male lead who isn't really human/female lead who repeats a certain phrase) and Angel Beats (pretty much just the immortality thing). I haven't seen an anime with the romance angle starting due to a glasses fetish though. So I guess Shakugan no Shana is pretty similar.
