1. If the Fallen can sense when Prime is dead, he can sense when Prime is alive. Hence, as you said why he was staying away. So, why didn't the Fallen teleport out of there when Optimus was heading towards him or fighting him? If he is truly afraid of a Prime, why didn't he retreat? He is far too proud to retreat but that then begs the questions as to why he didn't fight Optimus in the first film if he isn't really afraid of him. You see how that creates a plot hole? You see how the writing creates a dilemma in the plot?
Wait a minute...
The Fallen didn't fight Optimus in the first film because he's not...really afraid of him...despite the fact that ROTF...showed he was afraid of him?
Swuh?
You're asking me why a fictional character didn't teleport constantly to avoid death in his battle with Prime? Because he's a fictional character, and writers wanted him to die, not port in and out, obviously. The same reason the fictional cops in THE DARK KNIGHT don't get any shots in on Batman or evade his blows. They're supposed to go down.
2. Why didn't he send in more Decepticons then for the first movie? If the cube is so important, why did he only send in a handful of Decepticons? Why didn't he send more of them in for the second movie? You know, when you are losing a battle, you send in more troops if you want to win.
Why didn't who send in more Decepticons?
You're asking me why a fictional character who wasn't even seen in the first film didn't summon more Decepticons in the first film? How the hell should I know? I didn't write TRANSFORMERS. Ask the writers.
3. The Fallen is irrelevant because he wasn't intended to be in the first movie. But, instead of keeping the writing tight and trying not to expose loose ends, they wrote a script in 2 weeks to get it in before the writer's strike.
Uh...they had three months. The Fallen wasn't mentioned in the first movie because they hadn't decided to use him in the second movie yet. Hey, I know, let's condemn David Goyer and Chris Nolan for not showing Harvey Dent in BATMAN BEGINS, and then daring to bring him into THE DARK KNIGHT.
PLOTHOLE!
(Falls over laughing)
Sam knows what the shard is capable of. He witnessed the events of the first movie.
Then he knew the following:
1. The Allspark turned regular machines into mindless killing machines (I can't remember, did he even see this happen?)
2. Megatron wanted the Allspark for that purpose
3. Overdosing on the Allspark was fatal
Now, you assuming that he would know that the shard could bring Prime back to life based on those two things is laughable. Nevermind that he would have had to GET TO Prime to use it.
He is also running around with Autobots, particularly Bumblebee, who know what the cube is capable of and what is can be used for.
Except that, again...Bumblee may not know this, and there's nothing to suggest he would. All that happens when the shard activates at Sam's is that things turn into mindless killing machines, so that's what Bumblee, like Sam, has to go on.
Sam told them to dump off Optimus in the middle of a desert so yeah...he can get access to Optimus if he wanted to.
That wasn't Sam, I don't think, that was Agent Simmons, and that was after Sam had reason to believe that he had something that would heal Optimus. You're suggesting he would have had access to Prime before that? How?
It is also lol worthy that you mention Sam not knowing what the shard will do when he doesn't know what the **** the Matrix will do.
He has an inkling. Jetfire says it's connected to the energon machine, and that it has "an energy like no other".
Besides, I'm pretty sure Jetfire absorbed the shard when he powered back up. So Sam couldn't have used it to revive Prime after that.
Please answer my question as to why the Fallen didn't just go after the Matrix first instead of the cube. You seem to be avoiding that for some reason.
What the hell are you on about?
You're asking me why The Fallen, a character writers didn't decide would be involved until ROTF, didn't show up in TRANSFORMERS to go after the Matrix instead of the cube?
1. Because as ROTF shows us, Prime existed, he was afraid of Prime, and he had Megatron and the others to do his bidding.
2. Because he didn't know where it was, I would say. That was the whole point of the Primes hiding it, so that he and the Decepticons couldn't find it. The Fallen only found The Matrix when Sam did and he was able to steal it. Before that, he didn't know it's location. Which is why the Decepticons wanted Sam.
Please...stop pointing out things you don't like or understand and just randomly labeling them plotholes. Even after having the term explained to you, you clearly do not understand what it is.
