Whoever gave this episode a 6/10 did so unjustly.
The reviewer in question does bring up a good point that the series did well without any need for a flashback, and I actually second that notion. It certainly did not need a flashback.
There's plenty of options to choose from when you want to present a backstory and dedicating a whole episode to doing so wasn't necessarily the best choice.
BUT - This episode was nothing less than pure excellence. The simple fact that they went with the choice of dedicating this whole episode to a flashback and not another alternative is NOT a good reason to give this episode a 6/10 - completely unjustified.
The way it was written and presented was marvelous. Any questions that you had at the ending of season 1 will be answered in this episode. This leaves the writers to be able to more easily focus on the actual plot that was left behind after Season 1 and not having to add any backstory/flashbacks in further episodes of Season 2. This choice of presenting story is therefore (imo) better in the long run.
Approaching the story with another alternative could've very well ended in a mess, and thus I'm glad that the safer option was taken.
Remember, simplicity can be done intricately - 10/10
