I would dearly love to stop watching this show. Really, I would.
But it's such a train wreck I can't take my eyes off it. A weekly s#!tstorm of terrible plotting and writing.
And this latest episode has to be a new low point for the show. They've spent FIFTEEN EPISODES on the quest for the spear of destiny, building the artefact up as this powerful device that the Legion must never get into their possession and the Legends must protect at all costs because it can 'reshape reality'. FIFTEEN EPISODES, mind you.
So in the 16th episode the Legion have seemingly won. The Legends are trapped in an alternate reality, and the spear destroyed. Checkmate, you'd think? Not a bit of it. Because Sara figures out how to beat the Legion and put the world to rights: Time Travel.
That's right. You heard me. Time travel.
Just...travel back in time to before the Legion won and stop them winning. Duh.
So basically all the spear did was change history? Really? Because if that's true, then that's FIFTEEN WEEKS COMPLETELY WASTED.
Because Thawne is a time traveller. And the Legion can time travel. And it never occurred to these three criminal masterminds that they didn't actually need the spear at all because THEY CAN ALREADY TIME TRAVEL?
Which kinda makes them the Legion of Dumb.
No one needed the spear.
And in a show about time travel where the protagonists can time travel, it really never occurs to the time travellers that time travel is a really useful thing to be able to do, and travelling in time might just solve all their problems until five minutes ago? Seriously?
And the Legends are going to back to 1916? Why? Why on Earth would they do that? Because their earlier selves are still there and more importantly, the Legion of Dumb are there too. But the spear has existed for 2000 years, so why not go back to 1913 and dig up the field before World War 1 actually starts, dipsticks, or to 1900, or 1000, or whenever.
Not that it makes a difference because altering your own timeline can't be done as you'd create a paradox which would...
Oh, I give up. Really. This show is just SO BAD!
FIFTEEN WEEKS (sob)!
The point of the spear (pun intended) is that it rewrites reality minus the paradox effects of Time Travel.
as to the plan to timewarp back before reality is altered, well it is their last best shot and undoing things and restoring their powers, Martin's memories and Vixen.
Of course with the Waverider as a toy in Star Labs, well, they may have a....small problem.
