Poly-Juice-Potion

Rating: 9/10 (1 December 2010)

First off I really liked this movie.
I would actually say it is the best so far in the series - due to the darkness and the evil that was So much missing in the last movie.
There is one thing that made me puzzle though.
In Harry Potter and the chamber of secrets the trio is planning to go down to Slytherins champers to ease drop on Malfoy to see if he is he direct decenter of Slytherin.
To do this they need to make the Poly Juice potion and this takes very very long to create.
So they only go later in the movie after the potion have brewed for weeks even months.
And then again in The Prisinor of Azkaban The impostor being Mad-eye Moody have to steal ingredients from Snape to make more potion as the ingredients is VERY hard to get a hold of and VERY rare.
At the start of Deathly Hallows part 1 we see all character drink the poly potion and that is all good - but they drink from Mad-eyes canteen and he keeps it.
Then at the weeding they are suddenly rushed away as the death eaters show up and go to London.
The Trio then decides to use poly potion to look like the 3 employees in the ministry and changes into them to be able to enter.
There is only passing ½ day (1 night) from they come up with this idea until they carrie it out.
------ So we have just learned that this potion is extremely rare, takes very very long time to brew and then out of the Blue they just happen to have a bottle in Hermoiness bag (just in case)....
This seems like a bit of a stretch to me.
.....
But as I said at the start I very much liked the movie...and I look forward to the final part 2.
