Well I just got back from seeing this "Movie" and while certain aspects were entertaining I have to say that for the most part I was very unimpressed to be honest. At times I kind of thought that I was watching a crappy remake of a combination of TOS episode "Space Seed" and TWOK. I mean seriously, they even had to redo the scene with Kirk and Spock but with the roles reversed and Kirk dying instead of Spock??? WTF??? One would think that they could at least come up with an original story line and not use the same subject matter that was used in TWOK. 
Well without going into a big rant about it I'll just say that this one gets the thumbs down from me. 
My cousins know little about Trek but they saw it and said one thing. "I don't know if I like. It was fun though"
I came out saying the exact same thing.
To me the originality was the problem at the end...and jumping on a warp core didn't help either...
Additional:
I think as far as the "True Fan" is concerned there is essentially only two types of fanatics...
The Obsessed and will watch whatever it is no matter how bad or good the writing or acting.
The Faithful Commonly known as the snob that doesn't give anything a try because nothing can do it better than the first....
I get both. But it's just entertainment. Mostly I see people cater to what they've had the most initial exposure with. Kids growing up in the 2000's like Enterprise. That was their Trek. I liked Voyager and took a long while to warm up to DS9 and B5. It's still hard to watch the older series but I still respect it. Today's kids will see this Trek and swear upon it the status of best ever.
I've always wanted alot more out of Trek. It just sux that Rick Berman and JJ Abrams are who we got stuck with because both have undervalued the enormity of what Trek is and what it can do to inspire generation after generation. At least Star Wars got it's Day of Greatness. Trek hasn't seen it yet. These films are likely the best they'll get but I hold out hope for a Timothy Zahn or Tom Clancy to give a Trek Movie Script a true Royal treatment that both inspires the mind and the heart. I want Nolan...(Christopher) on a Trek Film. I think if we gave him just one film he'd blow it out of the park. I've seen his other works. I like Prestige...I saw that other film...Memento. (I didn't like it) he's a great writer when he has the time but Hollywood turns everyone into a assembly line and it's getting disgusting.
I've never watched Seinfeld...but they did there Homage to Wrath of Khan. They made it there own...I saw this the other day and I thought...wow I didn't see the ending coming...and yet it fits so well.
Well Done
