I enjoyed some of Paranoia Agent, but ultimately I found it disappointing, some parts were funny and others were interesting, but the majority lacked a clear focus, a sense of commitment or any genuine surprise. The series can be roughly compartmentalised into the comedic episodes, which were too frequent, and the story episodes, which weren't as suspenseful or well paced as I would have hoped.
I'm just offering my opinion though, so I hope nobody takes any offence, but if they would like to argue otherwise then I'd like to hear their views.
