What did you think of the Transformers 3 Ending? (Spoilers)?

Well there really is no spoiler that I'm going to say, but just a few
things.

* He killed Megatron too quick lmao, Megatron was like depressed
halfway through which fails.
* It just seemed strange without Megan Fox, and I did not mind that
blond girl it just didn't seem complete but that's just eye candy.
* Starscream fails and is a weakling. That's all I got to say about
that.

and last but not least, the ending. I thought it didn't sound complete
like the previous two movie's epilogues. This one was a weak finisher
for the series. I still liked the movie. I was sad about IronHide, it
sounded very "irrelevant" when we saw what Sentinel Did. Was he
showing how strong he was?!?!?! ...

But yeah, that's what I thought. and a question, I watched when
Seymour Simmons kissed the US Government lady then I left, was there
anything after that during the credits? Thanks.
My brother also said that he thought it would be cool if they killed
Bumblebee. That would be a good scene, Shia and Bumblebee's strong
bond torn apart. That's a good reason I also liked the series, their
friendship.
