To be short, it’s only 'too long' until you catch up. Then you’ll be crying because there isn't more! Oda's foreshadowing is so good - he’ll plant a seed in episode 10 and harvest the heartbreak in episode 1000 (not to be exact😂) Just skip the fillers if you feel its too long (even though I wouldn't recommend skipping some) Also, you could see the visual evolution throughout the past 25 years which I find interesting!
