Watch if you must...

Rating: 4/10 (25 May 2013)

I've been using for a while a rating system that considers a "Watchability Factor", Acting and plot... The rating system goes from 1 to 10, with 5 points given to the "watchability factor", 2 for the acting and 3 for the plot.
The scoring works as follows:
Watchability Factor
5 - Spectacular! Worth watching over and over again
4 - Outstanding will watch several times
3 - Really good movie will watch more than once
2 - Good movie may watch more than once
1 - OK movie... but once is enough.
Acting
2 - spectacular, Oscar worthy
1 - Really good, enhanced the plot
0 - movie wasn't about the acting
Plot
3 - Spectacular, nothing else like it in the genre, nominated for Best Picture (Oscars)
2 - Makes you think well after, unique
1 - Interesting idea / story
0 - Run of the mill
The Big Lebowski??? Two points for "watchability", one for acting and one for plot... for a total of 4 out of ten. Really Good Movie!!!... Watch if you must...
