Yeah I kinda of agree with you on Episode 6. It had the weakest climax out of any episode, and the closet mystery being a mess doesn't help. There were better ways that could have been done.
Also, I think when people talked about you not loving the end of Episode 6 I think they mostly refer to the circumstances surrounding that last puzzle instead of the puzzle itself. I didn't think those circumstances were that exciting either, so hey.
