I worry that a rating system would reduce the amount of thought each reviewer puts into their decision, but it's certainly true that peer review isn't perfect. Famously, the Fourier transform was not published for several years due to a disagreement with Lagrange.

> When Fourier submitted his paper in 1807, the committee (which included Lagrange, Laplace, Malus and Legendre, among others) concluded: ...the manner in which the author arrives at these equations is not exempt of difficulties and [...] his analysis to integrate them still leaves something to be desired on the score of generality and even rigour.
