Structure of eternal sunshine of the spotless mind

The structure of this film was more different than the other films we've seen. This one was more confusing than the others. It was kind of rewinding back in time like all the other nonlinear films we've seen. It also went forward to help the audience understand what's going on. Both of them had their memories erased of eachother, but then they meet at the beach & it all starts again. This movie was pretty awesome! But I did get kind of confused.
