Oh they will stretch it out for another two. The next instalment will probably mostly feature in Mirkwood. Concentrating on the spiders and the Woodelves. Not sure if they will touch upon Dol Guldur though, with a mention in Rivendell ... they have to take it somewhere .. or was that their link to the Lord of the Rings trilogy?
The Riddle Game was a huge favourite. The expressions and tone behind the dialogue was hilarious.
I agree with Guardian & Rollinscat that another part was a bit over the top.
