The Children's Minister Edward Timpson has criticised the report, claiming it did not explain why chances to protect Hamzah were missed.
Another source from the Department for Education described the report as "rubbish." Christine Talbot spoke to Professor Nick Frost, the man who oversaw the serious case review and asked him his response to those claims.
A report into the death of Hamzah Khan has claimed that a similar tragedy "could not be avoided" in the future.
Hamza died after being starved by his mother Amanda Hutton. His body lay in a cot in her bedroom for almost two years.
Today the man who headed up the review says systems let the little boy down. He added that lessons will be learned and no one person was responsible.
But within minutes of the report being published, the Children's Minister said he had "deep comcerns" over the review and claimed it failed to fully explain "missed opportunities".

Hazel Dow tells Calendar that although she had concerns about Amanda Hutton and her family, there was no way anyone could have realised that four year old Hamza Khan had starved to death.
Chris Kiddey reports from the Serious Case Review into the death of Hamzah Khan.
The children's minister Edward Timpson has requested answers to ten key questions following the publication of a serious case review into Hamzah Khan's death.
Here are some of them:
- Whether or not one of Hamzah's siblings was assessed by social care workers after reporting domestic violence to the police in December 2006.
- Why no assessment was carried out in April 2009 after police reported to social care that Hamzah's mother Amanda Hutton appeared to be "under the influence".
- Why an assessment was not conducted in January 2011 when the school of one of Hamzah's siblings reported low attendance rates and that the child "appeared physically neglected".
The father of Hamzah Khan tells Calendar he is "shocked" that a child starved to death in twenty first century Britain and says he doubts anything will change after today's serious case report hearing.
Aftab Khan says today's serious case review will not get to the bottom of how his son, Hamzah, was allowed to go unnoticed by authorities and starved to death in his cot aged four.
Hamzah's mother, Amanda Hutton was found guilty of manslaughter by gross negligence and sentenced to 15 years in prison.
