Haha, maybe not fair to call long.... I just maybe carried away because I got bored with a specific kdrama series.
I came from watching western/american series, which run for years, many seasons, 4-8 seasons. THAT'S LONG!
Actually what I found attractive about kdrama series is that they were SHORT! Only 1 season, 16 episodes, and it's DONE. No cliffhangers for next season, only to be canceled. It's a whole story, really like a mini-series I'd say, it has a beginning and an conclusive end.
But since I got so used to watching kdrama (nearly 130 series now) I've begun to think of them in terms of long, short, engaging, boring etc. And yes many series are difficult to finish... they're good but so difficult to get through.
Mr. Sunshine, Korean Odyssey, those kinda series I found particularly hard to get through. Great series I gave top notch rating, but took me 2-3 months to get through.
I'm not a robot, went down like a milkshake. Flower of evil was not like a milkshake, but it was just so ENGAGING that time just flew by and I finished in a weekend.
Now that I've watched some more jdrama, I do also find some series that are only 8 episodes and 45 minutes can be long because they're not engaging enough.
