There were some really strong parts to this episode, namely the interviews with the creators of Space Invaders, PAC-MAN, and E.T., however this summation of the first years of the video game industry left quite a lot to be desired.
Instead of actually starting at the beginning of video game history, we start in the late 70s. In turn, crucial elements of the video game industry's foundation such as Pong was only mentioned in passing and the Odyssey and the even earlier revelations such as Tennis for Two were completely skipped over.
What also doesn't work this series' favour is its tendency to jump around rather than tell a fluid story. Suddenly jumping to the (brief) history of Atari midway through an interview when it could've been mentioned earlier and randomly going back to Heinemann and her tournament after already having moving past Space Invaders were both clumsy moves in my opinion that broke up the flow of the documentary.
Other than that, I thought it was a bit of a weird move to not even mention Donkey Kong, although looking at next episode's synopsis I can see that we will probably learn more there. I'm honestly not as phased by the mass amount of graphics and visuals as others seem to be and did find the story of the marginalised Jerry Lawson to be fairly intriguing, even if (as another reviewer points out) he may not be as revolutionary as the documentary paints him out to be. Overall, it was fairly interesting and even with its flaws I look forward to what rest of the series has in store.
