"Invincible" comes out right after the emotional ride of "Runaway Dinosaur", at the start it seemed like it felt like a huge scale episode, it ended up exploring on Barry's character even after he already went to the speed force development plot line. The episode is also quite fast paced as the finale now nears its premiere and all the drama and action are now escalating.
In the episode, Barry starts out feeling over confident after his speed force experience. It felt like it was quite relevant given the circumstances the episode presented, but then again it felt kind of useless considering Barry was already given so much closure and development in the last episode already. It was nice that it was shown that Barry was now a completely different guy after the speed force, but it wasn't really fleshed out how him being more optimistic and encouraging was a sign that he was losing fear and the episode tried so hard to explain that fear was a good thing. In the end, and most especially in the end, we finally got the pay-off and consequences to Barry's actions and it was quite heartbreaking. Wally also has a subplot once again about wanting to help in the Metapocalypse and of course a set up for next episode as it is the season finale. The seemed average at best and does well at setting it all up. However the revelations done in the episode with missed opportunities. For example, there wasn't a real shocker to Zoom after finding out that Barry and The Flash is now back, the "Metapocalypse" didn't really seem all that large scale except at the beginning of the episode and Black Siren was just there for the sake of being there. The CGI and action however was for slow-mo type scenes and sadly, it just made one scene in particular look a whole lot artificial and seemed like a video game. Nonetheless, it's the ending which most people are talking about in this episode and it's quite well deserved. The way it was handled was quite unexpected just as you thought they wound end at a certain point, it goes on and further erupts. It was devastating, all the more considering last episode's story line and it probably is the push Barry needs for the season finale.
Verdict: 8.5/10
