I just finished playing through episode 4.
Aside from a few weird moments in the previous episodes, I've enjoyed the game(s) so far, and I enjoyed most of the 4th instalment.
When getting towards the end of the episode there are 2 major moments where I felt that the game went below standard and ruined just a bit of the experience.
1: When Clementine asks if we can go search for her parents:
Why in the hell isn't that an option? "Sure we can go look for them tomorrow morning. We don't have much time, but we wont leave Savannah without giving it a shot" (or something to that effect). Then you (would have) spend(t) the next morning looking for her parents. Of course you wont find them, but dammit - how come it's not even an option. All we get is a [LIE] option? Are we really in that much of a rush to get out on a stupid boat - which is a horrible idea anyway (and one which we can't reject) - that we can't look around for 4 hours?
2: When Lee gets bitten:
I really found this to be a case of dumbing down a character, because the plot required it to be done.
"I'll just look behind this board, by sticking my hands behind it and rummaging around"? A seasoned zombie killer wouldn't kick down the board, or push it aside?
It struck me a somewhat out of character - although granted he does have a serious problem with checking his corners (second visit to the auto-shop comes to mind).
Of the two, I'm definitely most annoyed with the first. All through my playthrough I've attempted to do whatever seemed best for Clementine. My stated goal is that I don't care what anyone thinks of me - even Clementine - as long as she's safe and happy. Let's say I talked to her about staying behind with the doc. If she was up for it, it would've been fine by me. Of course I would've stayed too, since there's really no reason not to. (A boat... with Kenny? That sure sounds enjoyable...)
The above two things hasn't gotten me all "I will never play your games again" - of course I will. Episode 5 can't get here fast enough - but please no more plot convenient idiocy.
To end on a good note I will say that I loved the option to tell Kenny to go F himself! I've been waiting for a chance to kill him off, this was a suitable alternative I guess.
