Arrow S4 - 3.5/10
This series has declined drastically over the past two seasons. A repetitive narrative and annoying supporting cast are the biggest problems. Green Arrow doesn't even seem to be the star of the series anymore. If this show is going to survive they need to ditch Team Arrow and the soap opera sub-plots, get back to the show's vigilante roots and dip into the deep library of DC villains to fill out the antagonist roles rather than these cardboard cutouts bent on world domination. All that being said I'm out for S5 so it may be too little, too late for many fans like myself.
The Flash S2 - 6.5/10
I'm still enjoying this series for the most part despite it starting to show similar signs of fatigue present in Arrow. Most of the supporting cast is decent and the villains are pretty strong. Hopefully the series can maintain momentum heading into next season and not trip up as Arrow has.
DC's Legends of Tomorrow S1 - 4.5/10
Strong production value and an interesting premise aren't enough to save this series. The acting is downright terrible in spots (Wentworth Miller, Dominic Purcell) and the core narrative drags. Most of the situations we find this reluctant band of heroes in feel far too contrived and not enough is done with the time periods and the people or heroes present in them. Lots of potential but unfortunately not enough was done in S1 to warrant me returning for S2.
