Query: The Worst of the series, period

At every step, unless you are under the age of 12 and have no conception of anything, DH4 has a conceit that says "our audiences are so dumb, we can sell them anything." Attempting to play upon the non-technical majority in the seats, the viewer will be asked to buy into such stupidity as West Virgina becoming the nexus of the US power grid, or that natural gas can be directed like a detonation train through US pipelines. This would be more surprising if you didn't realize that this mess was directed by Len Wiseman, gaining a well deserved rep as the new Uwe Boll. Save your time and money, and skip this mess!
