It's safe to say season 4 has had its ups and downs. I've enjoyed it more than most, but I can acknowledge all of the flaws people have. 'Lost in the Flood' really showcased these flaws in what may be one of the worst episodes of the season.

Granted, there is a lot of good that came out of this episode. Oliver is actually trying to be the "hero in the light" that he spent most of the season talking about. For once, we saw him suited up in daytime. Sure, it was in the secluded Ark or Tevat Noah or whatever the heck they call it, but still, it was nice seeing the suit in all its glory. The action was also impressive. I'm sure James Bamford had something to do with that but it's always worth mentioning just how well they choreograph fights on this show and consistently keep it fresh.

While all the action was going on in the ark, Felicity had some family drama she had to deal with. Charlotte Ross is always good and Tom Amandes is no different as Felicity's parents, but there was no real reason to have this conflict at this point in the season, when all focus should be on the main issues. If it would have been handled 5 or 6 episodes ago, perhaps it would have had a better impact.

Also making an unnecessary appearance was Felicity's ex-boyfriend and worst Arrow villain of all time, cooper. Other than doing a few deeds for Darhk that ended up being irrelevant, there was no need to have him appear in this episode. Not to mention the fact that we already had to deal with Lonnie, who is still somehow snooping around the ark. The only thing of worth he has brought to the show is killing Ruve.

While all of this was going on we also had Thea under mind control. Not only did we all know she would break free of the control, but it's just lazy story telling. I always take it as a time when the writers can't find proper motivations for characters so they use mind control to throw a spin on things. Thea didn't turn out to have any sort of impact on the rest of the episode, so why even use it? Taiana also fell victim to the control of others as she was influenced by the totem that powers Reiter. But let's not talk about the flashbacks.

Overall, I appreciate Oliver doing what he says he was going to do all season in "fighting in the light" and inspiring hope, but the execution for the rest of the episode wasn't there. It was directed by Glen Winter, who has directed some of my favorite episodes with 'The Calm', 'The Promise', and 'Broken Dolls', but he's also had some rough outings like this one. Seems to be the theme of Arrow lately, inconsistency.

+Fighting in the light

+Fight scenes/choreography

+Smoak drama was well acted…

-…But why in this episode?
