Since I've already voiced my opinion on Ep2 in a dedicated thread, I'll just say this...
This episode will be a complete disaster and no amount of work will save it - even if TTG would magically cause Sean Vanaman/Nick Breckon to write it.
The series stumbled out of the gate in Ep1 and Ep2 deepned the flaws of this series even more to the Mariana Trench level and I can't imagine one final episode to somehow redeem it.
And it'll hurt very much, because it'll make this the worst TTG series in existence. Yup, worse than Minecraft. Because, see, with MC, Telltale said right off the bat that it's for children. The story is light and never was advertised as a game up to the high TTG standards - and, with additional 3 DLC episodes, Telltale doesn't even pretend it's not a cashgrab anymore.
But Michonne was changed from DLC into a fully fleshed out miniseries and had tons of potential. TTG could fill the blanks for an interesting character.
But what we got so far (and I doubt it'll change for the finale) was a generic - yet somehow worse than usual - TWD story with a lot of flaws and a high school-level of writing.
God damn ttg, still with these rehashes? First, the boys their clothes are Clementine's clothes ep1-3. The older boy kid uses Kenny's head, alongside with his hair. How lazy are you? Now you re-texture stuff. Also, what if the girls were burned by fire tho?
