FoolKiller asked if I liked Pearl Harbor: The answer is no. Personally, the only redeeming part of that movie was the attack on the base, as I otherwise was very bored the whole time. However I did like The Rock, Armageddon, and I guess Bad Boys (so-so).

I think the plot holes are something that only the real fans are really going to be pissed about. I noticed them, but I went in not really thinking about them (despite reading about them constantly on AICN), and by the end, I wasn't too worried about it.
The whole Barricade/Starscream/Scorponhook issue, IMO, was left alone to leave a clear opening for a second film. Optimus made it pretty clear at the end that he was calling all Autobots to Earth, and furthermore, Starscream's exit pretty much showed that he was off to gather more troops for the battle.
I think the question largely come down to who is going to show up in the next movie, and furthermore, how/why they will be fighting in the next one.
However, I will give into the fact that the single lines between Megatron and Starscream were a HUGE disappointment. But I was so caught up in the movie, I really didn't care to notice.
Spoiler topic:
The whole death of Megatron seemed like an awkward ending in general. Given that he is the main reason why everyone is fighting, it seemed like a pretty awkward cop out to kill him right away. But then again, if they would have killed Optimus, that would have been even more strange.
One must assume that Starscream takes the lead role again, but it just seems so likely that somehow Megatron will return...
Oh, and I agree that Peter Cullen rocks. Having the classic Transformer sounds (compared to whats on today, Energon last I checked) was nice, and it really took me back.
Other autobots thoughts: Bumblebee was awesome, as I really felt an attachment to the character. I liked Ratchet as well, just as before, but Ironhide really took off in my book. Not that I didn't like him before, but his pissed-off/bad-ass feel was a nice change. As for Jazz, not so much. He was a bit too "funky" for me to like him.
But, I definitely feel the need to create a few more Autobots or Decepticons in Forza 2, as I already have Barriacade as of now...
