Pretty good start for the season, nice sci-fi concepts, 7/10

Pet peeves: away team knew it had to be ancient Earth after seeing T-Rex, after riding an alien creature that looked exactly like a horse at the beginning of the episode...

I was sure that the Voth were going to show up when they said it was the dinosaurs' Earth, I think it's a miss not to explore that, but that ancient Martian civilization concept was also interesting. It's not scientific however as we know pretty well that Mars was already bone dry 65M years ago.
