The CW’s Arrow has been set for a fourth season and the Flash for it’s second! It is good to see the DC TV universe is in fruition with both shows being extended for another season. The Flash has proven to be a strong component next to the Arrow by showing that Arrow is no longer the only hero for the CW. If you have not been able to catch up with the first half of both Flash and Arrow then I highly recommend you catch up before the mid season premier on January 20th for Flash and the 21st for Arrow. There are lots of major things happening on both shows which helped pushed CW to set a new season for Flash and Arrow. For those who have not seen the shows and are interested in them you can catch up with the seasons on Hulu. Here are the trailers for the mid season premieres! (WARNING SPOILERS)
