Depends on what you want to get out of it.

Prometheus is a strange one. Crafted by master director Ridley Scott, featuring a plethora of rising young actors and released to a massively hyped viral advertising campaign, it seems almost inevitable that it should have been a smash hit. However, the critical response to the film has been surprisingly mixed.
Now, Prometheus is not a perfect film, its script at times feels slightly clunky, some characters are criminally underdeveloped and the picture is constantly pervaded by the sense that you never quite understand what is going on. The final point in particular has been harped on in particular by some critics and it's a fair point. It is true that Prometheus teases the audiences with plenty of tantalising questions, questions that don't necessarily get answered.
I personally didn't mind this, as I often enjoy attempting to deduce problems myself and so I found much of Prometheus' charm to lie within it's mystery. However if you dislike films that fail to tie every facet of their plots up, you may find yourself infuriated by Prometheus' devil-may-care attitude towards dispensing answers.
It is rather hard to talk about Prometheus without spoiling it, but I'm sure that most readers know the bare bones of the plot. If not, the film follows a team of scientists exploring a distant world which might provide clues to unlock the meaning of existence. Heady stuff, eh? Of course, things eventually turn to pot as the crew battle for their very survival.
One of Prometheus' greatest charms for me was the sense of excitement and adventure you feel when the crew of the good ship Prometheus land on an uncharted alien world. Modern science fiction often takes away the mystique and thrill of space exploration, but Prometheus' near future setting grounds it in a realistic way that really captures the "one small step" feeling of the crew as they step onto this brave new world.
I was also favourably impressed by pretty much all of the cast. Noomi Rapace is very convincing as the youthful but passionate Elizabeth Shaw, who has so much staked on the mission. Charlize Theron is ever reliable as frosty corporate ice-queen Meredith Vickers. It was also good to see familiar British faces in the forms of the excellent Idris Elba and usual funny-man Rafe Spall (son of Timothy). However the real show stealer comes in the form of the incomparable Michael Fassbender who seems to be physically incapable of turning in a bad performance.
Finally, there has obviously been a great deal of curiosity over Prometheus' relation to the Alien franchise (and more specifically the film Alien itself). Now, I really love Alien and was interested to see how Prometheus would slot into the canon. However, please, please do not go to see this movie simply off of the back of Alien. The two ARE definitely connected but are completely different films. I would recommend that if Prometheus intrigues you then you should watch Alien (mainly because it's brilliant) to provide you with some additional context (hell, why not watch Aliens as well? It's equally brilliant).
So to sum up: really good movie, doesn't really deserve the beating its currently getting, especially fun if you are a sci-fi fan, don't see it if unanswered questions bug you, Fassbender's great (like, all the time), Alien fans will get a real kick out of it, paradoxically it is NOT an Alien film.
P.S. I watched it in 2D so I can't comment on it's 3D counterpart, but it was actually filmed in 3D (like Avatar) so it's probably a cut above the usual rubbish.
