So many comments all over the forums that this series is too long. I admit sometimes the pacing gets slow especially during the union/political debate scenes but I thought they were all necessary to understand the background of the story. For myself I blame by limited Cantonese for not understanding some of the discussions of minimum wage and safety for construction workers.
In many ways I felt the show was able to shoot and keep every inch of film they had. Certainly if I were in the director's shoes and found the series to be canned for 2 years, I would insist on keeping as much in tact as possible, especially since they are going to leave the network.
I really enjoyed (what might be waste of film for other stories) scenes such as Drummer, Ronnie, and Hak Jia tying themselves to Ka Ming to prevent him from scratching his hives. Or the scenes where the group hauls around furniture and matresses for their band room.
Also read that some people thought the story did not explain the characters well enough (and simultaneously that the show was too long), are people really so lazy to have the entire character bio written out in bubbles during the their scenes or have 15 minutes of voiceovers where the characters talk to themselves or have the villain tell the hero his entire schema including how to take apart his weapons of mass destruction??
