Anvilicious: The book and 2019 TV series spell out Wells' message that the Martians were not so different from the British imperialists, who would come off very similarly to the less technological advances peoples they conquered in the 19th century. He notes that the British caused the extinction of the Native Tasmanians (a few of them in fact survived, although this wasn't known in Wells time-thankfully by now they have made a comeback), much like the Martians seem intent on doing in the TV series. This was arguably necessary at the time, since imperialism was greatly popular, and it was shown as such in the TV series (possibly also needed as a reminder for the modern viewers).
It Was His Sled: The Martians' machines are invincible, but they themselves end up dying of Earth diseases their bodies can't fight against.
The 2005 Timothy Hines movie:
Special Effect Failure: While the quality may be up for debate, the quality of the effects is not. The heat-ray was straight out of a '90s video game, the tripods clattered along independently of the surfaces that they were standing on and the night time was represented by superimposing starry night sky over some of the visible blue afternoon sky while being filmed in bright sunny daylight.
