Avengers: Age of Ultron: 6 - 10.
Ultron was one of the most laughable villains I've ever seen, and he was basically an evil robotic Tony Stark with none of the intimidation or the genuine humor of the latter. The Vision wasn't as impressive as I thought he would be. Powerful, yeah, but no personality. The Natasha/Bruce romance was completely forced, I was pretty pissed at the character death in the film (I'm not going to spoil it for you, but I think that the wrong character died; really thought it should've been Hawkeye because his death would've impacted people much more), and of course, Ultron was arguably the most disappointing villain in the Marvel series since Abomination (although nobody can really beat the abomination that was Abomination...yet). The Infinity Stone plot, as someone mentioned, was the most rushed part of the entire movie, and it was supposed to be the most important.
Scarlet Witch and Quicksilver saved this movie from a poor grade. They added something new to the team. They added a more immature perspective, compared to the older adults, which I thought was brilliant. And they weren't just "the twins." Their personalities really contrasted with each other wonderfully, and you could tell that aside from being born twelve minutes apart, they weren't carbon cutouts of each other, which a lot of people who write twins love to do.
Thanos better be all that I'm hoping for and more (I refuse to watch the Ant-Man film because that scumbag Hank Pym is in there.) And Deadpool had BETTER face him first (because Thanos really hates Deadpool). There should be an Infinity Stone in the Deadpool movie, and I'm going to be very disappointed if his interactions with Death are shunted to the side. Also, Death had better be brilliant as well, if she's there.
Overall, a very disappointing movie; it was really a tragedy that the best villain in that entire film was Thanos, who only had a minor speaking role after the credits.
Riddick: 8.5 - 10
Well, this is how you make a sci-fi action film. Add in some really awesome creatures (vulture-like beings, the Mud Demons - which are basically a scorpion with a tail that seems to be a snake head with horizontal jaws and no eyes - and, my all-time favorite, jackal-wolf things, one of which became a pet to the MC, Riddick. Now, he has a trilogy to his name, but I haven't seen the first, and I only saw the end of the second. But I learned enough from the movie itself to know what had happened with this murderous criminal. Exposition without boring the person being exposed.
The mercenaries who are trying to collect Riddick's head are awesome as well. The leader of the professionals (Johns) and the father of a guy that Riddick killed (the guy was as bad as they came, but dear old dad didn't know that), a woman sniper with many skills who is the second-in-command to the professionals (Dahl), the nutty, small-skills-big-ego leader of the bushwhacker mercenaries (Santana), his second-in-command and my personal favorite human character in this film (Diaz), along with a host of others whose deaths to the Mud Demons/Riddick actually made me feel something. Santana was the lone guy I hated, but even his actor did his job to make the audience hate his guts.
Basically non-stop action and survival and easily some of the most heart-breaking animal deaths I've seen (I even pitied a Mud Demon at one point, although I felt sorry for all of the animals, really, having to live on a crappy planet like this one.) And about the planet? About the animals? Those were awesome special effects.
It's not the best movie. Sometimes you just wish it would slow down and take its time to savor the fear of the individuals stuck on the planet. Sometimes, you want to know more about the characters, save Riddick. But one thing that this movie never does is bore you.
Much, much better movie than you normally see on a home screen. I have to say that it was worth watching.
