Unseen:
World War Z
Bums will be clenched! I find it hard to get bored during this one since it really doesn't sit still once it gets going. And it's ambitions are big as zombie films go... daring to try and capture the event on a more global perspective where so many are limited to a city. It has surpassed 28 days later, Dawn of the Dead, and really all of the other zombie films for me. It's just better storytelling and doesn't lull like the other tend to. Dunno if it's a good fit for you or not... if you're looking at the cast don't let Jessica Chastain's presence lure you in to watching it, she's not a big part of the film really. There's reasons to watch the film, she's just not one of them.
Passengers
This one at least has some discussion around it on the forum. It's a difficult one because I think it gets into that unknowable territory of directorial intention. Is it an ethically suspect film that lets itself off the hook? Is it a neck deep script with an ankle deep presentation? I can see where those questions might arise, but if you can suspend judgement till the end, and maybe sit with it for a while... I dunno. I think its got a lot to ponder, and good bones. The concept is solid.
Spartan
Nobody ever seems to watch Spartan. It doesn't matter what I say. I think it's got great flavour. If you want an action film, but when you get on netflix and look at the action genre, and it makes you puke, then watch Spartan. David Mamet wrote this movie. They talk like David Mamet characters. If you like that, then watch Spartan.
Demolition Man
Like Tremors, I don't think anybody has a bad word to say about this movie. I hate to think of it as a cult classic or something. I don't think you need any history with this movie to have a fun time.
Four Weddings and a Funeral
As you say, a good one to watch with your wife! It's not a hard film to take... I often just put it on because I need something that's a comfort and familiar and good. But there is heart here... and warm friendships. And... I duuno... as much as it may have been the quintessential rom-com at the time it came out, in retrospect, and in light of all the mass-produced, direct-to-netflix garbage they pump out in the genre today, I realize what a gem this is. Modern rom-coms are so awful. AWFUL!
Pirates of Silicon Valley
In it's day I think this film was meant to be kind of bitter sweet. It concludes with "likable" Steve Jobs reduced to a mere artist with no real relevance while the evil, corporate, greedy, talentless Bill Gates sits unjustly in a position of success. But I kind of see it as the belligerent asshole getting deservedly squashed by a better person, so I enjoy the story. It's well presented though... the story parallels The Social Network... without Sorkin's writing of course, but still it's strong.
Labyrinth
I don't think they put this much effort into being creative anymore. This is like watching Spirited Away or Wizard of Oz or some other explosion of imagination.
Rounders
Nobody ever seems to come away liking this one as much as I want them too. Skip it!
Detachment
I don't see this film being something you'd like. I wonder if 1SO would agree with me.
Tremors (seen a lot of it on cable though)
Fortunately it's highly rewatchable!
A Late Quartet
This one has done fairly well in the past here with those who've tried it. I would recommend it to you and say it has a floor of 73/100 and a ceiling of 90/100.
Endless Summer II
Another one that doesn't really get the sort of enthusiasm from viewers that I hope for, so maybe a skip? Then again... it's unique and often quite beautiful and fun. It's got some wonderful moments and leaves you with pleasant feelings! If any particular hijinks are not doing it for you, just forward 30 seconds or so.
Happy Gilmore
Most Sandler comedies are not good. For some people Billy Madison is the Sandler comedy high point. I don't care for it... his character is not likable. I like Happy Gilmore and his goal of winning enough money to allow his grandma to keep his her home. I like that the comedy is not mean-spirited. It's just silly. Most of the time it's Sandler taking the hits. It kind of has the sweetness of a Farley bros comedy without the crudeness. Carl Weathers and Christopher Macdonald are so great in their roles. Many many other familiar faces are also really good. Worth a try! I would love to hear that you had a good laugh!
Career Girls
The ceiling is high on this one. Really high. But, i'd still say, go with what you're in the mood to actually watch.
Pi
You've seen just about every kind of film under the sun... so I can't say that you'll never have seen something like this. But then again... the execution here is really something. Subject matter may not be all that compelling to you... kind of a weird schizophrenic, conspiratorial thing. It's short though.
Perfect Sense
I can put no floor on this. It could be a zero. I think you might not like it at all.
Edmond
Tough to recommend this to anyone. But I don't think it will be a zero.
