I prefer movies. I've always loved both mediums equally, but I feel like there's much more opportunities in a movie than there are in a video game. What I mean is, in a video game, there's only so much you can do in creating the game. Setting, characters, plot, etc. always get re-used, and there's nothing ever original again (oh look, another FPS). Besides the occasional surprises, I get kind of bored with video games. But with a movie, there's an endless number of plots and settings to deal with that nothing becomes a remake, unless by intention. A good example is The Artist, a black-and-white film made in 2012. No one expected that, and it became a surprise hit because it was so original and took people by surprise. Even an action movie as simple as James Bond can pack so much locale into such a short amount of time. Originality is always what I look for in any form of entertainment, and that's hard to come by in video games these days. Also, I find much more "replayability" in a movie than I do in a video game. Sure, there's a lot of side quests and stuff to find in a video game, but when I watch a movie for a second or third time, I always notice something different that I didn't see the first time. On the surface, it may seem that a video game has more than a 2-hour movie, but I find it just the opposite.
This probably seems like I'm picking on you, but try not to read it like that, I'm just putting forward my argument in a way which requires countering yours.
This is all my opinion, and no one should see it as an attempt to try and sway their own opinions.
I'm not sure why in your opinion that movies are always original. The biggest grossing film of all time is barely original at all, in fact, most of it is practically a carbon copy of Pocahontas if you take it back to it's basics, and Pocahontas is probably a carbon copy of another film. Avatar is about a large corporation that is searching for Unobtainium on a newly discovered planet. On the other hand, Pocahontas is about the British searching for Gold in the newly discovered 'New World'. Avatar becomes about the native Na'vi fighting for the survival of their home, whereas Pocahontas ends up with Native American's for their survival and their home. Both involve what could be called a sacred tree, and both of these trees can communicate with the native beings. In the end the big bad guys lose because one of their own falls in love with one of the natives and helps to turn the tide in the underdogs favour and in the end the underdogs win. So as you can see, that's because like saying "Oh look, another FPS", since those films are practically the same with different characters, locations and graphics. A lot of movie's are like this, mainly due to the actors in them. All Adam Sandler films, Vince Vaughn films, Steven Seagal films...etc (the list is quite massive) have very similar basics behind them, all with different characters and locations. You mention the James Bond films, they are quite guilty of this too, particularly the early films, a lot all have James Bond saving the world by himself with a few gadgets and him getting the woman, usually one that wasn't originally on his side. Austin Powers is a series which parodies this fairly well.
If you want things that surprised people, that happens in gaming too. I doubt many people expected Modern Warfare 2 to have the level in which the intention was to kill innocent civilians. I doubt many people expected for Bioshock to allow you to kill children either, but they did it, even if you don't physically see it you know that it's happening. There are lots of games out there that had surprises in them that no one would have expected. And the film in which you are referring to may have been a surprise, but that's because it is in a style that doesn't take advantage of the technology that we had today. If you took that film and showed it to an audience from around the time it was set, they probably wouldn't be that surprised by it because it was what they were expecting.
I do agree that you do notice things when you watch films for a second or third time, or even a tenth time. However, the same could be said for a game. So really in the respect, they are on par with each other. However, the thing that tips the decision towards games for me is that once a game is completed and released, that's not the end of it. A lot of games these days get DLC so that you can continue to have fun playing the game as it introduces new areas and things to do. You can also mod a good amount of games yourself too, allowing you to download what could be considered unofficial DLC. You simply can't do this with films, no matter how many times a person tries to remaster them. After all, all remastering does either removes something that wasn't liked previously, such as Jar Jar Binks in Phantom Menace. In reality, there is very little that is different with the film, and it isn't really new content either.
