Let's just work with what's been on screen and off through the end of Clash of Kings to avoid spoilers. What has she done?
She outsmarted Ned Stark and had him arrested before he could leave KL and throw his support to Stannis. But, it backfired on her b/c she didn't control her son and he beheaded Ned, leading to the Northern Rebellion in which much of the Westerlands was pillaged.
She dismisses Ser Barristan losing a great ally to the Throne and giving him to Dany.
She issued absurd declarations requiring Tywin to send Tyrion to KL to become Hand of the King. Tyrion totally dominates her at Court, giving her the shits in a critical situation to take her out of commission. Tyrion brokers Myrcella's marriage behind her back and she loses control over one of her children. Tyrion steals Tommen away before the Battle of the Blackwater as insurance for himself against Cersei. Cersei also hires the Kettleblacks to be her personal guard, appoints one to the Kingsguard, and has no idea of their background or loyalties. They are bought as spies by at least Tyrion though ACoK. She also called Joffrey back from the city walls which almost lost the battle, but for her father and Mace Tyrell's attack to Stannis' rear.
