4. Ace Ventura: Pet Detective Jr. (2009)
Somewhere, at some time, an actual human person typed "Ace Ventura: Pet Detective Jr." onto the front page of their finished screenplay and handed it over to somebody else. Then this was made out of that script, with no hint or irony or being ashamed lingering in the air. Why? How? The fact that the public weren't even interested in a sequel to the semi-popular Jim Carrey franchise says it all, to be perfectly frank. But taking out Carrey entirely and setting the plot around the character's 14-year-old, Pet-obsessed son... that's seriously low. Any fans of the original, OK-ish movies will recognise some of its classic tropes at work here: there's a bit where the line "Aaaaalll righty then" is said, which proves about as fun to hear again as a punch in the ear, surprisingly The plot is, as you'd expect, ludicrous, though not in an endearing way or anything: Ace Jr.'s mother gets incarcerated and - teaming up with his grandfather - he sets out to, like, stop that from happening. Look, you don't need me to insult your intelligence by telling you it's bad. You don't need to read about it, even. Look at the title, for God's sake. Have some respect for yourself, won't you?
