This is one of those anime that gives you a deep feeling somewhere within. You might not like it necessarily, but it has left an impression nonetheless.
To be realistic and pragmatic:
- The plot feels slightly unreal.
- The characters - bland.
- The ending - absolutely insane.
And yet there's something within the thoughts and images that catches your attention.
To be even more realistic and pragmatic:
If you desire a break from the usual, and are prepared to face something slightly different, slightly weird, and not necessarily that good, then go for it.
It is definitely deep and original.
