I agree but, I felt all of these feelings towards Alien 3 more than I did towards Aliens 4. First of all Alien 3 had two plotholes in the opening scene that are way too ridiculous to stomach.
Plothole 1 How in the hell did the queen lay an egg in the dropship? She could barely fit in the leg. She was only in the leg for about 10-15 minutes. Even if she had time to grow one of those cocoons in that time period there is no way it would fit inside that space with her.
Plothole 2 What if the queen by some miracle figured out a way to lay an egg on the dropship? Was Ripley too lazy, too tired, or too stupid to check the area of the dropship where the queen hid before going to sleep? Ripley had experienced something similar to this during her first encounter with the creatures. In reality Ripley not only would have checked the dropship but, she would have also done a diagnostic of the ship to be absolutely sure there were no alien life forms.
Plothole 3 What in the hell was the alien doing for the majority of the movie? We saw how effective the creature was at killing the crew in the first film who had decent weapondry to use. The aliens showed they were fairly inteligent in two previous movies. 99% of the characters in Alien lacked the wits, resources, and experience to fight the creature. After being exposed to the prisoners for a few hours the alien must have known they didn't stand a chance against it. Why didn't the creature just slaughter everyone in Alien 3?
In retrospect alien 3 is somewhat of a combination of the first two films. It takes the idea of having just one alien from the first film and the idea of people being stranded on a planet from the second film. The only thing that made Alien 3 unique was the humans didn't have any effective weapons to use this time around. Therefore, most of the few encounters we do see between the alien and humans had action scenes that were either lackluster or confusing.
Lackluster scene:
The decision to kill the alien with the toxic waste is arguably the most bland action sequence in the whole series. The alien was briefly seen during a few seconds of the whole sequence!!!!
Confusing scene:
Why didn't the alien kill only one person(Andrews) in the mess hall? The alien had already killed a few people and must have realized that the humans had no threatening weapons that could be used against it.
The thing that irritates me the most about Alien 3 is it makes Ripley's heroics at the end of Aliens pointless!!! As far as I'm concerned the series with Ripley ended with 2 because Alien 3 had two many plotholes.
This is my take on your Plotholes:
P1: Whos to say one of those facehuggers didn't jump on the ship while they were waiting on ripely? Though some assumption or gives a care is needed,besides there wouldn't of been Alien3 if there wasnt
P2: Well maybe she was too scared out of her mind when the big ass queen showed up on the ship. She probably assumed it didn't have time to lay an egg,and no facehugger could of gotten on the ship anyother way. Again its the assumptions of the character/situation.
P3: Its not the M.O. of the creatures. Like Alien it killed waited,killed waited etc..ALiens there were mass aliens so the gang mentality ruled like anyother creature..I also believed they tried to create that susupence like in Alien. Besides what good would it do if it slaughtered everyone in the cafeteria.
Lackluster scene: I didnt mind killing it with the liquid metal,it was different and it fitted the movies style,crude and barbaric in ways.
Confusing scene: I answered this in P3,its not the aliens method to just do sencless killin's. It kills,rest,kills,rest,etc....Far as alien intellect,not sure how much it can recognize weapons,etc...
*theres gotta be certain assumptions,and situations that suggest something in another,cant explain everything. I know it makes scenes scratch your head,but /shrug its the way it works sometimes..
Quick say on Alien4. Like one poster said it was crappy fun until the hybrid was introduced. That has single handledly the worst lookin creature put on screen,lol. Whoever desinged that needs to have a alien burst out of their chest,along with the director for allowing it.
