What you didn't see in Nemesis:
(WARNING: Spoilers! Sort of...)

Alternate take of the emergency transporter scene:
Data: "Oh! Look captain! How convenient. A little tiny 'emergency transporter' button that will fit inside my arm!"
Picard: "Why, Mr. Data, doesn't a transporter require lots of computer power and energy to do the transfer? Doesn't one usually require a large room full of kit or at least a small ship like the runabouts???"
Data: "Well, yes, Captain. In every other Star Trek movie but this one that is true. However, Rick Berman is a tool and couldn't plot his way out of his own house. So we have this. Oh, and I got a writing credit..."
Picard: "Oh. Very good. Transport away, then."

Deleted scene after disabling Scimitar:
Picard: "Number One? Did I order the saucer section evacuated before I rammed it into that ship potentially killing everyone in the forward compartments?"
Riker: "I don't recall, sir. I was ogling my wife. Does this tunic make me look fat?"
Picard: "Good enough. Deanna is $0 HAWT. And I 4m $0 l337. I need something else to h4x0r. Did you see me send an IM from my chair? I am so l337!"
Riker: "Sir? The tunic? Does it make me look fat? Sir?..."

Deleted scene as Remans board ship:
Geordie: "Sir? If we have intruders on board shouldn't we send in all those security people we just passed out rifles to? We only sent like... 6 or 7people."
Picard: "Hmmm. Not a bad idea. Oh well. I'm sure the 6 or 7 people we just sent will handle it. Good thing the command staff is safe."
Geordie: "Ummm... Riker and Worf were the first ones out the door, sir...."
Picard: "Oh? Oh my. Well, no time to worry about that now. Now... before I ram this ship... wasn't there something I should do? Oh well. More h4x0r1n6."

TheReal#1: HI. IM THE CAPTIAN. ASL?

Deleted scene on planet where B4 is found:
Picard: "Mr. Worf. Break out the SUV. This looks like a fun ecology to fuck up."
Worf: "Yes, Captain. Perhaps we can also try some burnouts and wheelies?"
Picard: "Sounds good! Hope there's nothing alive out there, cuz we's about to get busy!"
Data: "Shotgun!"

Lines cut from scene in Romulan Senate
Shinzon: "I want to free my people. I want peace."
Picard: "Umm... didn't you just take over the Reman AND Romulan government? Aren't you like in charge of everything?"
Shinzon: "Errrrr... you know I hadn't looked at it that way... Well, nice meeting you. Bye."

For true scathing sarcasm, see Roger Ebert's review.

And finally, some real insight from Unca Willy:
"The script that I read for Nemesis was about people. John Logan is a HUGE fan, who knows every detail about TNG. He infused the characters and plot with detalis that would make a Trekkie drool. He understood why people cared about these characters, and told an incredible story. I still haven't seen the final cut, but everything I've read indicates that they got away from that. I have heard that on more than one occasion the director proclaimed that he didn't care about Star Trek history and continuity. It seemed like he really didn't respect the fans or the franchise, so they ended up with yet another action movie with robots and laser guns."

"So... you wanna kiss? See what that's like?"
