Sophocles really knew how to make a tragedy that's for sure.
the first play plods along nicely and then you are hit with a real shocker, it is quite moving and you do feel for Oedipus.
The second play was pretty weak, this may just be me struggling with understanding what's going on but it seems that Oedipus gets told a prophecy and then just carries it out. It feels like Sophocles was a bit stuck for ideas.
The final play is back to being very good, lots happening and a crazy amount of death.
I have not really read much in the way of plays but overall I did enjoy reading this. The parts by the chorus were very good at explaining what was going on and keeping you glued to the story.
About this version of the book? It is missing one vital part, some background on the story, or maybe explaining some scenes just to help those new to the story. If you are reading this for the first time I would look for a different version which has a bit of a guide to it.
