Theres ways of giving constructive criticism without the attitude. Using the words "suck" and "lame" are pointless, try to expand your vocabulary with something a little more descriptive and less threatening. Do you really think someone is going to respect your views if they come across as a personal attack on a person?
Despite what you may think, positive comments do help you get better. In much the same way criticism tells you what you did wrong, positive comments tell you what you did right, this is just as important. Positive comments also go a long way to show you have looked at the movie from all angles and are not just out to put people down. Your views will be much more respected if its obvious you have considered all angles.
I'm not sure if you relize this, but from our point of view you have busted in here shouting you mouth off, harshly criticizing everyone in sight. Why not take a while to compare your posts to others, watch how they manage to give helpful advice without starting a hate campaign. Your views are very welcome, and if you can manage to convey them in a manner that isn't so antagonistic they will be appreciated a lot more.
Lets dissect your first comment and see if I can show you it from our point of view
What a long and boring Movie!
Not a great start is it. Instant criticism like this will put everyone on their guard and the rest of your comments wont make any impact. Start by discussing the movie to show you watched it properly. Pick out one or two parts that you felt could use some work. And instead of just citing them as "boring", try to explain why.
It kept going on and on!
You've already made this point in your first sentence. Once is enough, unless you intend to expand on your views. Repeatedly pointing out something you feel is wrong is just insulting. I'm sure you don't want to insult people do you.
Don't mean to be rude, but that's criticism for ya!
This is basically saying "I don't mean to be rude, but hey, I am anyway". This shows you know your comment is rude. You don't have to be rude to get your point across.
Let's be more creative and learn how to act.
"be more creative", "learn how to act" about as useful as "make a better movie". You don't explain what is wrong with the creativity or acting, or more importantly, explain how to improve. Not to mention the negative attitude of that statement. "I feel the movie could be improved with more invention and a little work on the acting" says exactly the same thing with none of the abuse. It still doesn't say much but I think it would be more gratefully received.
Acting is important in making the film look real. Without good acting skills, even with Professional effects,
Good stuff, so why spoil it with...
the movie will suck.
What value does that add?
Why did you think Star Wars made it this far? Is it because of the light sabers, yeah, sort of. BUt really, it was the acting is what made it good. Carefully plan out your ideas and script
Again, useful stuff. Might have helped if you had some tips about how to plan and script. You pretty much imply he didn't plan or script it at all, which we both know probably isn't true. Maybe you could have pointed out a few parts you felt could have been scripted better. Just saying its all bad doesn't give him much of a starting point. Anyway, theres some good points in that sentence which you totally nullify with...
so that it won't look so lame.
You just have to get that pointless dig in at the end don't ya
It's just advice, not a put down, k? Understand that.
You suck, you really suck. No I mean it, you really really suck. I'm not saying you suck tho. Reminds me of a Simpsons blackboard quote Adding "just kidding" doesn't make it okay to insult the principal
Keep it up though.
Lets keep this bit
