It was okay up until the near end where the writers committed a plothole drive by and hit and run on the audience. There you are underground trying to find the Deux Ex Machina to continue the story and then Flint fills you in on matters you either didn't care about or forgot about. " I didn't care about Girl Stinky's evil plan but since they brought it up...what was her motivation?" What about Sal being her accomplice for two decades? What took so long? Oh, She a mermaid? How did you find that out...not going to tell us okay bye got the plot device now going back to the story. Maybe it's just me but did anyone else feel the same?
