I like this just for the novelty of it. i.e. How many movies have I seen released in 2017 Marvel schtick: Guardians 2 & Spiderman ?
Guardians 2 was "that bad Star Trek episode" I'd seen so many times before. I was very underwhelmed. Fun characters, but crap story.
Spiderman wasn't miraculous but pretty good for what it was. The twist wasn't amazing, but cool, I think I caught it about 2 seconds before the reveal. Maybe I'm just slow.
A more interesting question (maybe the one being asked) is which movie I've seen did I like the most. Spiderman was better than most other movies I'd seen, or seen for the first time anyway. Though 'Dredd' (2012) really impressed me. It's disappointing they didn't make more (though they may), then again that's often a double-edged sword, if they did make more movies (or have a TV series) it will probably ruin the coolness of the original. So perhaps that's best.
It's a good movie if you're into action/sci-fi and not too averse to somewhat graphic violence (or able to tolerate), it's recommended.
