There are more strong events we are experiencing through the fourth season, as there seems to be a new struggle for both Connor and Abby with life in the Cretaceous era. At the same time, A.R.C. It seems to have been rebuilt and updated with two different new members this time. On the other hand, he is still looking for old Connor Duncan his friends, and do not expect to find him obsessed with those strange creatures.
They may have hit a brick wall plot-wise, but they're already well on their way to delivering a pleasant filler of a season that you actually want to go through the motions watching.
