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: Peggy Sue Got Married
Ensemble Darkhorse: Walter, played by Jim Carrey. Surprisingly a naunced role, because despite being a wild and crazy guy ("Whatever Walter wants, Walter Getz!"), he's a fucked up guy in the 1980's who is hooked on cocaine.
"Funny Aneurysm" Moment: After Peggy Sue returns from her time travels, Charlie said he would cut his right arm off for another chance to reconcile with her. Ronny, Nicolas Cage's character in Moonstruck, is missing a hand due to an accident at the bakery after his fiancée dumped him.
Special Effect Failure: The opening shot through the mirror uses body doubles, and it's done well enough that if you aren't looking you won't notice the "reflection" being out of sync - but is jarring when you do.
