I just thought Terminator Dark Fate was simply... okay. If you forget about Terminator and T2, it is I guess a passable action flick, but nothing more than that. If you start actually thinking about the plot and backstory, you realise the whole script makes little sense. It says it is a direct sequel to T2 yet makes what happens in that movie totally pointless. The reason for Arnie being in the movie made no sense.
In terms of a Terminator movie, I just couldn't help thinking, "okay this series is done now". It adds absolutely nothing new, and shits on what came before it.
