There were a few scenes that, IMO, will warrant re-watching, particularly the last one, but only if you watch it on mute because Chris Carter should have his keyboard taken away from him. Oy. He needs to never write about religion -- anybody's -- ever. It's nothing in the least bit damaging to the MSR, if that floats your boat. The last scene, with Mulder and Scully smiling a lot and holding hands is great, but CC's dialogue hurts my ears and addles my brain. HOWEVER, the song right at the end put a stupid grin on my face. I'm not spoiling that though.
Miller and Einstein are fine -- no threat to the MSR and frankly, no threat to be the new agents, IMO. Lauren Ambrose was good, but Robbie Armell, bless his heart, reminded me of a little boy dressed up in his father's suit.
HATED the hallucination stuff... seriously dumb.
So, basically there was a fun M&S scene at the beginning and a great one for the eyes at the end, not so much the ears. Please, CC, pass the keyboard to the next writer in line.
There is one scene in the hallucination that ties into the overall story. The rest I'm fairly certain is due to CC smoking something and wondering how many close ups of shapely butts he can fit in there.
