I would imagine that most people have at least heard of this 2005 film and maybe about the fact that it is one of the largest box-office failures of all time. I watched it for the first time ever a few days ago and while I do think it is pretty bad, I don't think it was awful enough to deserve the reputation that it has.
The movie begins in a confusing way with a US civil war naval battle taking place on the USS Texas which was transporting a shipment of Confederate gold coins from Richmond Virginia to, i don't know where. I thought i started the wrong film.
Then we immediately jump to modern day Mali, where a disease has broken out and World Health Organization Dr. Eva Rojas (Penelope Cruz) is investigating the source of the disease and trying to help out. While doing some sort of investigation (alone, away from civilization, in a country currently in a civil war) she is attacked and her research is taken from her. She avoids being killed because Dirk Pitt (Matthew McConaughey) just happens to be nearby when it happens.
the scene in the picture doesn't occur until much later, but I knew it would happen during the opening credits
She ends up on a treasure hunting ship to recover from her wounds and through some dialogue that really isn't important ends up going on a mission further inland to look for the gold that was on that ironclad boat that was in the opening minutes of the movie. This is where my real problems with the movie begins

Why Mali? Why did they choose a landlocked country for a speedboat adventure? The ship they just left, the research vessel where Dr Rojas is recovering on is clearly in the ocean, but now they are scooting up the river into Mali, which even if there is a river wide and deep enough for a speedboat to get in there - which may be true, like most people, I have a low level of knowledge of the topography of Mali - it is certainly beyond the range of fuel capacity of such a small gas-guzzling vessel that they are using for the journey. Maybe the boat was airlifted in, i dunno, I'm not a boat guy but the logistics just don't make sense to me.
A bunch of battles break out between them and military forces that are very Rambo-esque in the way that very few people get shot, especially not our heroes who have very little difficulty running directly into machine gun fire unscathed.
This only invites question about how the USS Texas ended up there in the first place. As the name "Ironclad" would suggest, the ship was made of iron and had a very low clearance and would almost certainly sink after it ran out of fuel 100 miles or so into the 4 and a half thousand mile journey from Virginia
FAR!
There are plenty of other physical impossibilities that take place in this movie but I'll let you discover them for yourself if you bother to watch this. Action movies aren't meant to be realistic, so these elements alone wouldn't deter people from going to see the film. There are a lot of theories out there as to why the movie lost $90 million or so but one of the main ones is that Matthew McConaughey wasn't a box-office draw in 2005 like he is today. He was at that time mostly a rom-com star and hadn't seen a budget anywhere near this one up to that point.
If I were you, i would watch this movie anyway, not because it is an epic action movie, but because of how absurd it is. It is also a rather big piece of history as one of the biggest bombs to ever happen in cinema.
