Well... some reason I don't feel like sharing the plot because it's a kind of hard plot to describe without telling the whole story and spoiling it for those who haven't seen this yet. But anyways...
Most people I have heard from that have seen this film have gave it positive results. So my expectations were surprisingly high coming into watching it. And it didn't blow my expectations to China, but it certainly exceeded my expectations.
The cast which features Will Ferrell as the main character, Megamind is absolutely 100% perfect in this role - his classic voice just fits the character's personality perfectly. No flaws. Tina Fey (Roxanne) is very solid in her character's role - which surprisingly became a near-main-character. Jonah Hill as Hal and the *SPOILER ALERT* so called superhero turned villain, Titan is perfect as well. Maybe it's because his character looks exactly like him - I mean it's creepy - well, maybe not exactly, but Hal definitely has some resemblances to him in real life. No flaws, either. Brad Pitt as Metro Man is pretty good - not amazing, but he wasn't bad at all. And last but not least, David Cross is awesome as Megaman's um.. yeah... sidekick named Minion (whatever you call that random creature) is quite good as well. As mentioned in my Kung Fu Panda 2 review, it's quite easy to play a animated character well - I just base them on how well their voices suit their respective characters, and I didn't find anything wrong with any of the actors lending their voices in this film.
The movie is hilarious. I was laughing so hard during a couple scenes - the laughs themselves were worth a watch. Let alone the awesome soundtrack the film has to offer.. And the film just finds a way to keep you entertained one way or another. Now keep in mind, I am not a adult so I will find movies like this quite enjoyable (most of the time) so some of you (adults) might not find this as good as I did, but some of you may like it, who knows?
Again, I am not gonna go too far into the plot or story of the film since it can easily give a spoiler or two just by giving a tiny recap, so if you want to be spoiled by a reviewer, head over to a little thing I like to call Wikipedia.
But anyways.. I give this film a 9\10 - worth a watch - especially for kids and teens and maybe even some adults will enjoy this as well. It's worth a watch if you ask me.
