There's a lot of stuff wrong with the story of this episode but it's mentioned already in the other reviews.
What isn't mentioned however is that the battle scene between the Waverider and the leviathan is just plain idiotic. Rip hunter clearly is feeble minded. Why else would he have positioned the Waverider in GRABBING range of the leviathan. He could have easily positioned the ship higher and out of reach, shooting it from a safe distance. The whole grabbing/fling/crash and subsequent danger of imminent destruction was therefore utterly absurd and the result of extremely stupid script writing imho.
