The new WOTW had a stupid plot. You’re allowed some illogic in a thriller, but if it’s too stupid the audience loses their temporary suspension of disbelief, and now you’re no longer making a thriller, you’re making a comedy because the audience is laughing at you. WOTW is a funny movie, but not in a good way.
The one flaw everyone pointed out was keeping Wells’ ending where the aliens are done in by germs...at a time when the Germ Theory of Disease was fairly new this was novel but now it’s a cliche. But I loved it for the great action scenes (that rushing train!) and the entirely unexpected melancholy tone and subtext of how groups of people respond to a calamity. There are logical flaws in Hamlet and Macbeth too. No one cares.
