Okay, so I do think that Okabe was overacting a tad too much in the first half of this episode. This stands out more than usual because the acting in this series was always so great, but that’s where the melodrama got a bit too much, especially because it caused him to not think of the obvious solution of using the time machine to travel further back in time. I also think it was a bit cheap for this episode to just “announce” that Okabe tried every possible way to save Mayuri: I understand that it was for time issues, but I would have liked to have seen Okabe to try some more and exploit other possibilities.
On the other hand though, this episode got right back on track when Christina returned to the main picture. Her level-headedness was exactly what Rintarou needed, and the plot turned really interesting with the actual introduction of leaping beyond the 2,5 hours of the previous episode. The big twist at the end that Suzuha turned out to be John Titor makes perfect sense. The prospect of severely altering time in the next episode also makes yet again for one hell of a cliff-hanger.
I do have to wonder what Suzuha meant with that the Y2K problem was one of the moments where world lines greatly converged based upon the choices made. Of course I was only 12 when it happened, but was it really as important as the Gulf War? I rather would have guessed that 9/11, the invention of the internet or the birth of social media would have counted as that.
Rating: ** (Excellent)
