Back to the Future and Beyond 2

Finally watched the last episode of "Back to the
Future."

Of course the major mistake here has always been
the fact that it was impossible for Doc Brown to
make a working flux capacity in the year 1885.

In 1955 there was no plutonium and thus there
would be none in 1885. So even if he had the
materials to make the flux capacity, he does not
have the means to make IT WORK! I mean it is not
as if he knows ahead of time when a lightening bolt
will strike (as he did in episode 2)Doc Brown had
Mr. Fusion installed in 2015, but once again the
materials to make this unit were unavailable in
1885.

A minor note, Marty and the Doc are standing on
the edge of the ravine and Marty says they can't
wait around 18 months for the bridge to be
finished. He says this on Friday 4th Sept 1885.
According to the notice board at the ravine the
bridge is due for completion in the Summer of 1886.
Even giving Summer it's full 3 months, that means
that the bridge would be completed by the end of
August 1886, less than a year away!

Beryl was often texting during the films and arrived
up to 15 minutes late for the start but said that
'overall they weren't bad'.
