I thought the episode was a little underwhelming as well; and honestly feel, that the CW would do a much better job with SG & story, than how CBS handled Flash. Everything seem forced & contrived or convenient.
It was fun episode that captured my imagination of what could have been. Cisco would have been great with Winn...love to see those two in a pi%%ing contest. Kara & Barry did have good chemistry; however, SG & Flash really didn't gel to me. Cat was over the top & felt out of place with comedic one-liners. Like someone said...this should not have been the episode for the Jimmy/Kara love bloom. Although I understand using Barry's charm to be a catalyst; I feel it fail terribly.
The acting was subpar for CBS episode and the action, what little there really was, was not that enticing. The villains was subpar...Live wire seemed more bark than bite. Did enjoy the SB backstory...but they had to rush right through it because of time restraints. Which lead me to say, this should have been a double episode deal, to allow ample time for more character & story development. The whole episode seem rushed & proceeded too fast...and I think that's why it may have suffered & a bit underwhelming. It was not the best episode, could have been better, given the magnitude & character involved; but, it was great to see Flash with a major superhero, other than Green Arrow.
As far as timing of episode....I think it was important for CBS, the episode debut off the same weekend as a more notable team-up occuring, in the likes of Superman, Batman, & Wonder Woman. Episode being out of sequence with CW was not as important to CBS as taking advantage of the BvS release. Little disappointed that there's no sense of other common superheroes being on either of their respective Earth's.
6.5 out of 10 mainly because acting, setup, story, action, & a bit corny. Good parts no doubt Kara & Barry chemistry, i will say Barry & Winn chemistry as well, Barry's intelligence & compassion,
