I've watched 140 episodes so far. Please don't get mad when I ask this, but does Nami ever become more bearable? I cannot stand her in the show as she is in it right now.
She's always so bossy and beating the hell out of the rest of the crew. She also acts like she's the most important one there constantly even though she's not. Always acts very self-important.
Nami beating up the crew has always been a gag because she is mostly the straight person of the crew. Nami cant actually beat up Luffy because he is straight up rubber. Battlewise she is probably the weakest in the crew and this is more to balance her role in the crew to get the guys in line.
Without spoiling, Nami is absolutely loyal to Luffy and will have her moments. She will also be shown as a very caring person even to other people she just met.
Remember that Nami literally carried the burden of an entire fucking island.
