I must concur with eyeresist, on this matter. The third season seems so fresh and vibrant compared to the others. When the baton was passed at the start of the overrated 4th season ... somehow, it all went awry. The magic was lost and it just sort of plateaued.
The ideas were there, like spending a lot of time on Vulcan. The very thought of which suggests and implies a mysterious, exotic landscape and very regal, authoritative characters and rich, vibrant costumes and customs. And what did we get? Archer and T'Pol filmed in a rock quarry with a red filter over the camera lens. We got a galloping sehlat that wouldn't climb a mild incline to attack them and it was easily chased away by a local with a ridiculous knack for making animal sounds. I mean ... what's with these people making this shite?
-ENT- started delivering half-assed attempts at pandering to hard core Trekkies, instead of novel science fiction stories, like they'd done just the season before. Whatever. Praise You, Jesus, that I didn't have to pay for it, out of pocket, like I'm going to next time a STAR TREK series comes along ... that's all I've got to say. I would've been grumpy. Very grumpy, indeed.
