Honestly the most boring "must watch" anime I think I have had to endure
The Melancholy of Haruhi Suzumiya is one of those anime that most agree is one of those series everyone should watch. As such, about this time last year, I started watching it, and after 3 episodes dropped it as it didn't interest me. A few months later, I tried again, and dropped it again as it still failed to interest me. But this time, this time, I was certain I was going to finish it... So I downloaded the episodes onto my phone, and watched it on the bus to/from work, so it was either Haruhi or nothing to entertain me for an hour and a half a day.
I finished it, in 2 weeks, but it felt like 2 months.
