The Tunnel Movie (2011)
Pretty mediocre found-footage film. I really liked the backdrop, the environment was fantastic, but ultimately I thought that it could have been better... There were a few scenes wherein I couldn't suspend my disbelief which was a problem... Also, the fake-interviews-within got annoying after a while. Interesting at first, but otherwise not effective.
Grave Encounters was better. ;)

The Avengers (2012)
An absolute blast... Started slow, but ultimately wound up having a lot of fun. Mark Ruffalo as The Hulk really surprised me; hands down best Hulk in modern movies yet. Loki was brilliant, as was Robert Downey Jr., Thor, and Captain America. I agree with Angra, though; as someone who hasn't read the comics, Hawkeye and Black Widow just seemed lame and unnecessary; they pale in comparison to Hulk, Thor, Ironman, and Captain America.
Thoroughly enjoyable. Makes me want to watch
Ironman,
Thor, and
Captain America again.
Highly recommended, and worth seeing in the theaters.
