I thought the same about the latest Spider-Man movies to be honest. I'd just got used to Garfield and then Sony sacked him because he couldn't be bothered to attend a meeting in the hotel he was staying at. Initially when Marvel announced the new English actor who's also a comedian I just groaned, I hadn't heard of him before to be truthful, but like I said before he's starting to grow on me.
I didn't think much of Doctor Strange to be honest, I didn't particularly like the comics when I was reading them as a kid, you just knew he was going to use some kind of magic and get himself out of the pickle he was in which got boring after a while.
The character I personally feel is Marvel's best but has not been given justice on the big screen is the Punisher. If Marvel did Garth Ennis Punisher they'd have a blockbuster on their hands.
