the most annoying character?

When I rewatch it I fast forward through all the family stuff. It’s pretty boring. Just keep it on our friends. Capische.

Janice and ma..

Too many to choose from but easily the top 3 had to be Tonys Mom, Janice, and AJ.

Useless characters to me were the Barese crew (Ally Boy and Larry). They just wrote them out of the final season like they cease to exist. Others site the standards like Janice, Tony's kids, and Carmela but they're missing the point of their relevance to the story's overall plot and Tony's arc.

I think you'd need a lot of patience to spend time around Paulie Walnuts and not find yourself getting irritated by him.

They are all annoying, but a lot depends on how a certain scene was filmed. Some scenes were made to justify certain people and actions, and some to emphasize our distaste for others, but, when you get down to it, think about their motivations, there is no justifiable character.

I then it's best to think of characters by which period or position. Here are my top most annoying:

AJ & Meadow as teenagers
Dr Melfi in sessions with her therapist
Noah
Junior Soprano on house arrest
AJ's teacher who Carmella dates

I put Tony's ma, Janice, Ralph, and Carmella into différent categories
