These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Dante's Peak
Cliché Storm: Protagonist lost his spouse in the same disaster many years ago and is still hung up about it? Check. Jaded superior who insists that they need proof only for him to be, of course, wrong, and subsequently die a Karmic Death? Check. Most annoying character who refused to come down from the mountain and thus endangered the lives of the others dies? Check. Dog survives? Check. Big final blow-you-out-of-your-seat special effects sequence? Check. Token Romance? Check... And yet, for all that, it still manages to be good.
The dog surviving is more of a Necessary Weasel than a Cliché. Anyone who kills a dog has just lost their audience, even if it is fiction.
Ending Fatigue: The volcano has blown, he's trapped in the truck, the team discovers the blinking light, the rescue, fly away. Could've been condensed. Still a good movie which tries to get the science right.
The part where lava suddenly bursts through the inner wall of Ruth's cabin.
The part where Ruth jumps into the acid lake. Especially the very thought of either doing that or crossing the lake, which you know will most likely burn through the hull of the boat, dumping you inside and causing you to most likely die a horrible death.
The skinny-dipping deaths at the start of the movie. They (mostly) use a Gory Discretion Shot by panning away, but still...
The pyroclastic flow, basically the non-video game equivalent of the Advancing Wall of Doom, but it's advancing at something like 100 mph.
The start of the eruption is pretty frightening if you put yourself in the shoes of the town. Bridges and buildings collapse, people escape on foot across roads where panicked drivers ignore lanes, and smaller cars desperately drive into the river to escape and are washed away. All under a sky rapidly filling with ash. The imagery and civilian responses are almost apocalyptic.
Squick: Let's say that you really don't want to fall into a lake full of sulphuric acid.
Third degree acid burns on the inside of Grandmother Ruth's lady parts. Dear Gods.
Forget the lady parts, her legs fell off afterward.
Visual Effects of Awesome: Although some CGI was used (specifically for the lava), the majority of the film's visual effects were done either practically, or with very large miniatures, such as the bridge sequence, and holds up quite well today.
The dam burst (the miniature was something like fifteen feet tall) and the pyroclastic flow are particularly impressive.
