More of A and less of B: speaking of a mixture of two things, he says there will be more of A in the mixture and less of B.
A is "the freakier side"
B is "the geekier side".
The word "side" means approximately "aspect" or "character".
Both "freakier" and "geekier" are comparatives, but that's not important. It would mean the same if it said "more of the freaky side and less of the geeky side."
Now, "freaky" can mean strange or eccentric, even frightening.
"Geeky" means inclined toward fascination with technology.
So, paraphrasing, "more weirdness, less technology" in the makeup of the show.
