Spiderman 3 was a better movie (only because it was less crap mind you)

Its hard to say which will have the edge in terms of sales though

Spidey would get smashed by Optimus.

As cheesy as the film Transformers was, the special effects (I watched it in my home theater) totally rock. Spidey? Not so much. It felt stuffed - that the director wanted to do so many things at the same time. It felt like that in X-Men Last Stand - crowded.

Give me Transformers - even Go-Bots over Spidey.

==> damn, I dont think we have seen the same movie
SFX were good
but the way they were used was so bad
For me, hey dont succeed to bring the robots in the reality ...

 Bzzzt WRONG

SPiderman made 305 million dollars domestically, Transformers made 320 million.

Spiderman three was a horrible movie with a ridiculous amount of flaws, who else was a little annoyed with the narrating and the random butler. 

Can we EVER AGREE on anything? Sheez ... maybe you need a new prescription because the movie I saw rocked. I am sorry if it looks like crap on your 12" black and white screen - but it looks great from where I am sitting ...

I'm with Stof. Both of those movies sucked out loud. Spider Man 1 was pretty good, Spider Man 2 was less good, but still acceptable, (despite the fact that Spider-Man is supposed to be able to lift ten tons and repeatedly punched Dr Octopus in the face, which would have liquified him instead of doing NOTHING) Spider Man 3 was just retarded. Especially that moronic scene where Tobey Maguire tries to act like a dick. "Mmm, check me out, I have mussed hair and a black suit...this gooey alien symbiote all over my body really makes me want to....DANCE!"

Transformers was retarded too. And if I was Megatron, I wouldn't have wanted the all spark. I'd have wanted that cube as far fucking away from me as possible, since it seems programmed to kill the shit out of the first robot that comes within 50 feet of it.
"Give me the all spark!"
"Here!"
"AAAAAAAAAHHHHHHHHHHHHHGGGGGGGG!!!!!!"

Spiderman 3 sucks donkey balls. I think Bay did the best anyone could do with a live action Transformers movie. Transformers truly showcases how great HD looks.

I think you are wrong my friend. Where did you get those numbers from?

Spider-Man 3 -> $336M (Domestic) | $980M (Worldwide)

Transformers -> $318M (Domestic) | $701M (Worldwide)

I personally think they are both ok movies.

I got two words. Megan Fox. She smokes that other fake red haired chick. Plus the Transformers was watchable. Spidey 3 made me cringe in parts.

==> lol
the cinema screen was perfect.

about the sales, I expect :

DVD sales similar for the 2 movie (huge in fact)
SM3 BR sales = 2 x Trans HD DVD sales

and yes the girl in Transformer was beautifull but I like Kristen Dunst too.
