I'll be brief:
Is it cheesy? Yes. Is the script and plot predictable? Absolutely. Is it still a lot of fun to watch? You betcha!
Here's the thing, most movies coming out of Hollywood are average at best and it's all been done over and over again. Rarely are you going to watch a movie today that's truly a classic. So, at the end of the day it comes down to a few things:
1. Is it visually stimulating?
2. Is it immersive?
3. Are the actors enjoyable?
4. Did I enjoy watching the movie?
5. Did it pass time well?
The answer to all five for me was an emphatic yes. In the end, while not a great actor in a traditional sense, The Rock is pretty much always entertaining and this movie was more or less a feel good, happy ending that you saw coming but there was enough tension and plot to make it interesting at all times.
Watch it, I'm pretty sure you'll enjoy it!
