Overall I loved TWD and most of the characters in it. In fact I'd go so far as to say that The Walking Dead is one of the most memorable games I've ever played.
But I think Telltale stumbled a bit with Molly. The great thing about all the other characters in TWD is that they are entirely believable. They seem like real people just caught up in extraordinary circumstances. The one exception to that is Molly.
The ninja acrobatics and the ability to apparently vanish killed immersion a bit. They should have toned that down a bit and made her bad@ssery a bit more grounded in reality. No acrobatics that a real person couldn't pull off, no Houdini disappearing acts, and no using a claw hammer like a superhero grappling hook.
