All good points I think you guy have really hit the nail on the head for the most part. To add to that...I also feel that now a days it is all about the money. Don't get me wrong Hollywood has always been about the money, that's why they make movies in the first place, but the fact that it is all about the money is even more prevalent today.
Case in point, you use to hear about actors turning down roles back in the day. If they didn't think the film was going to be a good one then they didn't take the role because they did not want their name associated with a poor film. Fast forward to 2014 and think when the last time you heard of actors turning down roles. It doesn't happen much these days because it's all about money.
Then you have what you guys were saying with special effects and bad scripts. They really go hand in hand. IMO scripts are rushed and poorly written because they think they can make up for a poor script with adding a bunch of special effects. The SFX may dazzle the younger crowd or the easily entertained, but anyone that is looking for a good well written thought provoking movie will see right through the SFX crap and see the movie for what it really is, just another cash cow...(can anyone say "Battleship").
There are some good movies out still in recent years...."Into the Wild, The Grey, The Hunter, Flight" those were all well written good movies with very minimal SFX. But there is for sure a lack of good movies out these days as compared to the past. There's a new MJR theater that just opened last Friday and I looked to see what was playing there on opening day. They have 16 screens in there and yet I could not find a single movie that even remotely interested me in the least bit to go see it. That's pretty sad if you ask me.
