In trying to get Barry's speed back, team Flash unintentionally creates a zombie - Girder. With Barry/Flash no longer there to help retrieve him, Iris comes up with a plan to use herself as bait to lure zombie-Girder back to S.T.A.R Labs, which Joe thinks is too dangerous to allow. With Henry shaken by the fact of seeing his son dissolved away, and Harry distracted by the blast putting his daughter in a coma, the team needs these fathers to concentrate their efforts on each other's behalf in order to address their immediate dilemmas.

The Runaway Feels
11 May 2016 | by SpoodermanDerpSee all my reviews

"The Runaway Dinosaur" is an emotional ride that back tracks a bit to give Barry a well done and well deserved development within the Speed Force while building great chemistry between the group and it's characters.

Right off the bat, the episode really does a great job at capitalizing and giving each character in the S.T.A.R. labs team or even the smaller characters enough time and spotlight to truly shine respectively. With a minor flaw being Tony's sudden appearance which really has no sort of relevance to the episode, and he's just there for the sake of being there. You can take out Tony from this episode and replace him with any other bad guy besides Zoom and the episode would've really played the same which is quite appalling. Now that we've thrown that away, this episode is really damn emotional and hits you right in the heart. As Barry fights to come back to the real world out of the very trippy speed force, as he does that he gets greeted by people who are special to him. This gave way to one of the most touching scenes the show has ever had since the finale in Season One which really hits hard. Barry in the speed force basically gives him the sufficient back tracking and eventual closure he needed that surprisingly wasn't explored as much to its fullest extent in previous episode. Kevin Smith also does quite a good job giving chemistry between the side characters and giving them hilarious lines and subtle mannerisms to make it all the more fun. The best way to draw a parallel to this episode to another property is probably Guardians of the Galaxy. It's weird to an extent, it balances humor and emotion, and it contains a whole lot of touching scenes involving moms and "Take My Hand" scenes.

+Emotional scenes with the speed force +Great chemistry between characters +Great subtle touches -Villain could easily be replaced with someone else and has no effect whatsoever.

Verdict: 9.3/10
