There's an easy way around the issue of watching things in order, such as in your Godfather example (or it renting TV series, which they also have available). Only put the first one in your queue. Then, once you've watched that one, put the next one in (and put it at the top of the queue if you want to see it soon). Thus, there's no worries about receiving a later installment before a prior one.
