Well what else would you expect from a sentient tree!
However, I would disagree with you saying Groot has “no redeeming qualities”; I thought Groot had a pretty great mini-arc where he went from a selfish bounty hunter to selflessy saving the rest of the Guardians. I also thought the “we are Groot” line at the end was powerful for a character that only says 3 words in the rest of the movie

I don’t really see how this is a problem; is Rocket a flawed character? Yeah, but that’s fine. The way he overcomes and learns from his mistakes is far more interesting than an infallible or “perfect” character like Superman (or even Captain America to an extent).
I’d strongly disagree with this opinion.
For me, The Incredible Hulk doesn’t feel like an MCU movie, the style just feels completely different, and not in a good way. The actor for Bruce Banner was uhhh not good in the role, I’m glad they replaced him. The CGI is also extremely ugly, the end fight between Hulk and Abomination ... yikes

I don’t actually disagree with this, even though I do in general dislike the first 2 Thor movies. Thor’s arc is pretty nice and I do like his character in these movies, it’s just that the rest movie is so dull and lifeless that I find it hard to sit through these movies in one sitting.
I totally agree with this, he’s certainly one of, if not the, most entertaining characters in the MCU. I do think he works much better in the big team-up films than his own movies, as he plays off really nicely with other big personalities like Thor and Loki, or in some of the later films, Spider-Man and Doctor Strange.
