I saw Sharktopus and Mega Pirahna. As incredible as it sounds, they weren't
enough over the top, and approached faster the limit of so bad it's bad rather than so bad it's good. Although I laughed at the scene where the giant pirahnas ate a US navy battlecruiser

- the movies needed seriously more of that and better over the top dialogue. Luckily and at the same time ironically, we were prepared for this possibility by drinking enough alcohol to prevent the brain damage these movies could cause - so I view it as a kind of exchange between different sorts of brain damage. If memory serves, Megashark vs. Giant Octopus suffered from the same problem.
We also saw R.E.D. and Alien Apocalypse during that movie evening. RED was ok, and Alien Apocalypse was actually not that bad. Whether if that is because of Bruce Campbell or some other reasons remains to be seen. Let's see what will be the next movie we'll watch.
