I rewatched The Day After Tomorrow recently. I saw it in the cinema when it initially came out and remember the special effects being so incredible, and even though it was a bit dumb, an enjoyable big blockbuster.
Yes I saw it in the cinema too. It's one of those films that crops up on rotation on TV here and while I take your point about its naffness I do find it agreeably lazy easy viewing if I happen to catch it. I like picking out some of the reliable tropes such as:
✅️ harassed boss who points and says "you've got 48 hours" (✅️ during a hurried on-the-move corridor conversation)
✅️ gruff manly sidekick who heroically dies
✅️ younger rookie sidekick who doesn't die
✅️ charismatic comedy relief homeless guy
✅️ sceptical government/military figure (VP in this case)
✅️ haunted president intoning "God help us all"
✅️ mildly eccentric English character (climatology professor here) who makes reference to tea and biscuits
✅️ other English sidekick obsessed with football
By the way, the football obsessive is well observed in being a Man Utd fan, but not so well portrayed in that we see him watching a match while muttering "Kick it. Kick it. Go on, kick it." When of course he'd actually be half out of his seat shouting "Get it into the fucking box you useless - WHAT? Oh fuck OFF ref you WANKER!" etc.
