I am not an expert in this space, so hopefully an actual expert will come by and clarify, but I am pretty sure that "The current consensus [...] is that there was no such thing as ‘the sea peoples’" is just flat out untrue. (IIUC, what is the current consensus is that they did not "cause" the late bronze age collapse). That colors how I read the rest of the review.

Edit: Personally, I enjoyed that particular addition to the plotline, as unrealistic as it is.
